Compact Disc Turns 26, Has a Bright Future
javipas writes "The Compact Disc was created 26 years ago, but apparently it is as healthy as 15 years ago, when computing versions of this format (CD-ROM, CD-R, CD-RW) made the market explode. Nowadays CD has been replaced in some segments, but not on the music industry, that continues to support it massively. The shy return of vinyl and the absence of real competitors make CD's future very bright, so it seems this birthday will not be by any means the last one we celebrate. Happy birthday!"

More and More car stereos, even factory stereos will play from an ipod or better yet a usb memory device filled with mp3 music. In fact Clarion recently released 2 new car stereos that cant play a CD, only digital memory formats.
I see the CD going away slowly as digital downloads become more and more popular, but that is completely dependent on DRM going away. I have enough friends and customers that are pissed at itunes DRM right now that they will not buy another song.
Do not look at laser with remaining good eye.
IMHO the iPod et al spells doom for the CD. As soon as 'the kids' can transfer music phone 2 phone there goes the music biz.
However, as burning and archive mechanism, why not, but no room there for the 'labels'
Physics is like sex: sure, it may give some practical results, but that's not why we do it.
I think Cds have remained so popular because they're cheap to make, small enough to be convient, and simple to lock down.
Why shouldn't we switch over to flashdrives? They're even better than CDs(smaller,more space, very cheap and getting cheaper,can't scratch)But they're easier to modify. It's hard for the average user to jailbreak/mod a CD. Not so much for new forms of media.
Although the hyper vigilance of Blu-Ray firmware updates may seem to contradict me...
Who the hell celebrates a "26th" anniversary?
I am shocked that the summary lists the music industry as the reason that CDs have endured as long as they have. The music industry enjoyed record CD sales during the 1990s. Those days are long gone. Online distribution is the medium of choice for that.
CDs have been relegated to the ranks of $0.50 disposal media storage for 650 MBs at a time. When this disc space is used so ~200 Mp3s can be "backed up" in case of Mp3 device or harddrive failure... then you can argue that the "music industry" is being supported by the continued usage of CDs. But don't be fooled... the only reason to keep CDs around is because of the need to cheap, disposal media distribution. Neither e-mail, online storage, or UBS memory sticks quite fit the same niche as the standard CD.
Support the 30 Hour Work Week!!!
You used to have to buy writable 650Mg CDs for $1. Now you can get a gig of flash, near infinitely rewritable for $7. Impervious to scratches, can survive several trips through the washer, and have fast read/write speeds. I cannot understand how TFA is so optimistic. When CDs came out, it would take weeks to download a full CD, now I can download a 720p torrent in an few hours. My HDDVD player has a Ethernet jack... so how long until we stop spinning discs and start slinging bits?

The truth is that vinyl never went away.
A few years ago someone at worked asked me what the last Rush album was that came out on vinyl and after some poking around I found out that they all had up to the latest (Vapor Trails, IIRC). The thing is that many people lost touch with vinyl but the die-hards* kept with it. I don't know if it's the nostalgia factor or even if it's true that vinyl is making a comeback but the bottom line is that it wasn't a matter of the vinyl not being there but rather listeners who didn't know where to look.
* Yeah, if you're one of the small percentage of all people over the age of 17 who can really hear the difference. Otherwise you're probably only fooling yourself.

Remember when AOL used to spew out those CDs to pimp their dialup service? I use to use them as coasters for my coffee cup.
I also remember AOL giving out so many floppy disks that I never had to buy my own since neighbors/friends just gave them to me saying "here, you can use these, right?"
Then when they changed to CDs, it took about two years before some people caught on that I couldn't reuse those in quite the same way...
Was a New Order album I bought because of the "True Faith" track (from the Bright Lights, Big City movie), which I just had to have. Of course out also went $1,200 on a Technics CD deck as well, because I only had tape and turntable at the time.
I don't have the disc anymore (I do have the box somewhere) but I have this distinct memory of CDs being a lot thicker and heavier back then. Anyone remember that?

I bet there is some occasional unexplained knee pain. And for some reason, compact disks can no longer eat bananas without violent diarrhea.

I don't like them and I nearly don't use them anymore. They have taken the place of the floppy disk for me - three out of four CDs I burn have some OS that I can boot from. ;-)
When I want to share some files, I put them on a USB-stick or a portable hard drive.
There was a time when I stored backups on CDs, but the hassle of organizing and searching them is just too big.
Don't get me even started on buying software or music
I hope 1TB USB-sticks will come about soon.
but I don't have kids to teach. It's easy, I just swap Microsd cards, and mail them any "non" mp3 stuff they had on it back.

Does anyone know how the CD came to be 5.25" in diameter?
Were the designers intentionally working with from the size of the floppy disk, which happened to be right for car CD players?
Or were they working to fit the same size as car stereos, which happened to be the same size as 5.25" floppy drives?
Or did they ignore both and just happen to end up that size?
Or did someone happen to have a 5.25" floppy drive in their car, and thought it would be great to read more than 1.2mb worth of data on a disc?
Damn_registrars has no butt-hole. Damn_registrars has no use for a butt-hole.
but how the heck do I return an MP3? When on the road, I've always turned to renting audio books from cracker barrel.
It's great because, depending on my time, I stop and get a new book if I want one. I couldn't do that with an MP3 or USB stick without my computer. I know ATT would pitch a fit if I tried downloading 12-16 Cd's worth of book Over-the-air.
I know of nothing online that rivals something like what Cracker Barrel has going on for $4 a week.

As a huge fan of DVD-Audio, it saddens me to see plain old CD still cleaning house. I guess the public at large just does not care about audio fidelity, or an immersive music experience.
CD is still good format for storing normal data in offices. I dont now mean any games what needs DVD's or HD movies, but normal office data. For sending photos it is great because you need to store photos in JPEG (or other) format so you get them to small size. CD is good unless you need to send all RAW photos what you toke in weddings or other similar situation.
What I really like about CD, is it's lifetime. It has be used to store music what can be still played. Only thing what makes it worse, is these new ideas to push DRM's to them what makes CD's more like use-and-throw-away medias. That is the about on music business. That feeling I have got from music corporations.
So I can still listen those 15-20 years old CD's on my computer or car stereos, but I am not sure can I listen CD what I can buy today from store.
Same thing is happening on technology, television gets digitalized and all standards starts to be changed every 3-5 years. Reminds me just from the Microsoft Office format.
I hope that Blu-ray disk is now such media, that can be keeped next 20 years. Altought personally I am scared that there is coming next media around a 2015.
Is it really so that old medias actually stored the data better way because it could be used longer? Like VHS, CD, Vinyl, paper etc? The problem is not the technology itself, it is on companies who wants money and more money by "inventing" better versions after a next one and pushing them out faster rate.
Someone recently asked if I'd send them a CD of some pictures. I looked at them funny, and then realized that not everyone realizes CDs are dead yet. It's like when Grandpa's on Life Support in the ICU, and the Brainwaves aren't registering, but you still go in and say goodbye. The best uses of CDs now is Skeet targets, and decorations. I just want a car stereo that can do DL DVDs for Mp3's and gives me options to play through a directory structure, and make / edit playlists on the fly QUICKLY. Then, I'll replace the monsoon system in my car, assuming I still own a standard 4 wheeled vehicle by then.
(for instance play Outkast /stankonia & /Speakerbox disc 1 & /Speakerbox disc 2 etc..)

What about coating a roof w/ used CD's!
I want to be the first to coat my roof (shiny side up) w/ nothing but metallica albums!
Really though, CDs are an O.K. medium to get music to your computer quickly if you have dialup. Remember that in the US broadband penetration kinda blows, and in many areas if you don't like the company that offers it your SOL. for $50 broadband fee / mo. you could buy like 10 new CD's (if that was the only reason you needed broadband it'd make sense)
And to those who say 1 gig flash drives, phooey They'll just stack up because no one will use 25 1g flash drives. I say a flash drive KIOSK that loads what you want to buy onto the drive you own right there instantly.
It's what 2 min to fill a 2 gig flash memory? Plug drive in, format /q, copy leave store, plug it in your stereo/comp/ cellphone, PDA, etc.

It may have a healthy future, but now it's severely overpriced. Initially they were expensive because it was new technology and expensive to build plants to manfacture the raw blanks, master, and press them. Over time we were promised that the price would come down drastically as the process matured. That was proven true with CD players.
Of course that turned out to be a lie with the media itself, and prices have risen steadily while the costs of production have plummeted. And the artists will tell you that they're not getting any more money out of them in mechanical royalties than before either.
Evidence of how badly ripped off you are in CD's is evident by the healthy profits made by DVD's which contain far more content, and cost far more to master and press, yet sell for nearly comparable prices. Until we Just Say No to overpriced music CD's we might was well just open our wallets to the recording industry and say, "Just take what you want."
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
Here' an example:
The Beatles, Hard Day's Night, the movie on DVD is twelve bucks at Best Buy. It pretty much has every song on the album in the movie. Twelve bucks.
The Beatles, Hard Day's Night, the CD. Has all the music, none of the movie. Price? Fourteen bucks. Same thing, but on media with less scratch resistance, less storage space, and oh yeah - no movie.
The reason why people aren't buying music is because it's not worth it. The price is artificially inflated, which makes consumers grumpy and unwilling to buy.
Weaselmancer
rediculous.
Yeah but those metal cans the CD's came in were great for sending out my own to friends.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
Why? Both my motorcycle and my cars have the ability to play music off my 16 gig USB thumb drives. (The car will use a 40gig Hard drive connected tot he usb in the back.
are you not looking very hard for stereos that do this? Also who the hell makes playlists in their car while driving? make your m3u playlists at home and selected them in the car.
Do not look at laser with remaining good eye.
You mean Laserdisc?
They were usually used for movies, and the video on them was actually analog, so your comparison to a record is very apt.
If I have nothing to hide, don't search me
Here is a rehash of the classic Beethoven's 9th story. According to legend, the president of Sony was presented with a prototype 11.5cm CD with a 60 minute limit. He demanded that the CD be capable of storing his favorite symphony, Beethoven's 9th, and it required a capacity of 74 minutes with a corresponding size of 12cm.
Damn, this post is total gibberish. But I guess the OP's point is that the CD is 26 years old and we still use it? In other news...the CD is the new floppy and people will keep using it until they stop.
Apple seems to be a good job of predicting (if not causing) future trends - first mainstream computer with a 3 and a half inch floppy, first PC to ELIMINATE the floppy (original iMac), and now first computer to get rid of the CD altogether (Macbok Air)
Your acquaintance is not the one out of touch, it's you. As has been noted, CDs make excellent one-off, disposable storage. Their capacity isn't great, but it's enough that if you need to send a few files over someone's way, you can do so without worrying about them losing your flash drive.

DVD-Audio has no killer features to balance its killer flaw: copy protection.
"Not an actor, but he plays one on TV."
of what you said. I failed to mention he wanted me to mail them (he is curently 3 states away). That requires more than a plain envelope and a few stamps, for best results, and no cracks, they really should be sent in a padded envelope.
Again, I agree w/ one-off disposable storage situation for sneakernet, it's fast enough, and easy.
But for flashdrives...
For a 1g flash drives they fricking come for free in a cerael box. They are like 2600 whistles. O.K. I am exagerating, but who doesn't have 3 of these lying around their house w/ nothing to do? I have two 512s, a 1 and a 2. + 3 1g sd cards he can get Far easier than a thumbdrive OR a CD. Also the value of a flash drive is small enough to not worry about losing it. 7$ after you adjust for inflation is like .50 from 5 years ago.
Sorry, I like to exagerate.

When the CD came out, it was cutting-edge. At that time, a 10 megabyte hard drive was considered huge and set you back more than $1000. Today, you can get drives 10,000 times larger for 10% of the price. There's no way you put any other 10 year old part on you computer today (unless there was some data on it you needed to extract). As cutting edge as it was, you still had to sacrifice sound quality with 16/44.1 sampling. That's why vinyl is making a little bit of a comeback. Why do we have to accept having such outdated technology? Actually we don't which is one of the reasons why the music industry isn't selling music like they used to.

I didn't realize the 16 gigers are under $50 now! WOOT! Scrap the DVD thing.
As for making playlists, sometimes a passenger will DJ. Sometimes you'll be sitting in a starbucks drive through, or stuck on I-5 for an hour moving about 1 mile. It's not a huge requirement but it shouldn't be impossible to que up 15 or twenty songs.
I was looking hard for steroes about a year ago, and didn't see anything I liked. I resolved to just re-allocate my money for that time, and stick w/ what I had until things get a touch better. I could have gotten what I wanted if I spent over $600 but for that, I'd put a computer in my car and be done. (thinking of going that route anyway, though time spent for that project isn't practical either)
What kind of units do you have? What kind of car/ bike?

The CD is still arguably the best premium format for buying and collecting music. They can be made inexpensively, they're pretty durable, you get some artwork and liner notes (though not as good as with vinyl), they're reasonably compact, and the audio quality can be very high indeed when it's mastered right.
The mastering process has become the weak link, with the ongoing "loudness war" where dynamic range of music is routinely compressed all to Hell.
The attempt to introduce Super Audio CD and DVD Audio turned into a farce. First strike against them was the ridiculous format war. Second strike was the ridiculous DRM they were saddled with. Third strike was their dependence on superior audio quality to sell the product -- something most people couldn't even hear, and the rest of the industry didn't care about. (If they cared, we would never have got into the aforementioned loudness war.)
Sorry, I have to disagree. They have a very bright future in the microwave.
No matter what you might like to think, the fact that they asked for a CD proves that it's not dead. Going back to your grandpa example, you seem to be like the person trying to wrestle your inheritance out of his fingers while he's still perfectly healthy.

Vinyl never went away but it's been nearly dead for a long time surely?
When I was a teenager in the 80s every small town had an independent record shop for niche tastes, major department stores stocked mainstream pop and classical records, and larger towns had a whole host of larger music stores with floors of records. These days you only find the niche record stores and the really big music shops have a "DJ corner" with vinyl. To be brutal, measure the floor space given over to vinyl in shops compared to other products. The retailers are only going to stock what sells. I think it's sweet and lovely you can still buy vinyl and some bands still release on it but I think it is nostalgia or for specialists. Speaking as somebody who can't give up his punk 7" singles! But could I be bothered to buy a new record? hmmm...
I mean you can buy new wax cylinder recordings but I am sure they aren't coming back...

I'm sure it's a technical answer but why can't, with 700mb of space available, one lousy kilobyte be reserved for metadata? If older players wouldn't like it, I should think it could be "hidden" after the last track.
It just seems silly that my CD player can't scroll the title of the track being played. Or that my computer can't pull titles and even album art without an Internet connection.

We'll I've added one new CD every year to my collection ever since. Now I have a whopping 26 discs! It'll only take me 1674 more years to replace all my vinyl, cassettes and 8 tracks.
I remeber the big CDs, they looked like vinyls, but digital.
Huh? To the best of my knowledge there have *never* been any commercially marketed CDs larger than the standard 12cm ones! (The obvious disadvantage being that they wouldn't fit in an ordinary CD player). The only other CD size I know of is the "mini" 3-inch/8cm one.
Perhaps you're thinking of the LaserDisc video format which actually predates the CD? They came in a variety of sizes, the largest of which was the same size as a vinyl LP, but looked not unlike a giant CD. Some later ones included digital sound, but the video itself was always analogue, albeit at better quality then video cassettes.

That should be "obsolete" of course. I fail at speeling.
a poorly recorded mp3 can actually damage hearing at high volume due to the "missing" audio data. you can actually see the missing sound on a good EQ, which forms an incomplete 'compressed' waveform, which your hearing is unable to deal with at high pressure (70+DB).

I seem to have derailed this discussion by claiming that "physical media" will become obsolete. Perhaps it would have been clearer if I had said "physical media for use as a distribution mechanism for music and data to consumers" but I thought people would be capable of keeping the topic of this discussion in mind while reading my remarks. If you need a reminder, take another look at the title of this Slashdot article.

I ... still back up to CD and DVD (depending on what is being backed up) in case the hard drive dies.
Why? I just back up my HD onto another HD. Are you doing off-site backup?

That reminds me... has anyone mentioned the SHM-CDs? Has it ever been discussed on Slashdot? There's not even an entry in the English Wikipedia. It seems almost unknown outside Japan. I was tempted to submit a news item about it once, but being lazy as I am I've never done it.
Opinions vary a lot, some claim the quality is similiar or even inferior to CDs, while others, possibly the majority -- the format seems rather popular in Japan given the increasing number of releases -- say the quality is noticeably higher.
Anyway, here's the Japanese Wikipedia page about the SHM-CD,and the summary from CD Japan:
No really they were, I used to program/build CD players for my job for >5 years.
The old mechanisms were lovely metal framed affairs will bushed bearings, metal worm drives or fast moving arms for the optics. The optics were proper optics on well balanced, nicely made actuators and the whole thing just stank of quality components and care and attention. Because they were well made, the characteristics of the system was consistent from one unit to the next, and the analogue servos were all tuned to match the system. They could play CDs with horrible scratches on them much better then modern ones and the sound quality was generally better because they had a proper DAC.
When I left that field we were using "low cost" mechanisms. This mean moulded plastic gears, one single senser fits all (if you know how long it takes to reach the end of the disc, why bother with a sensor? just ram it against the end stop) The lens is bubble of resin, the actuators were often horrible. On top of this the tolerance in manufactruing was bloody awful. The resonances, the bandwidth changed considerably between units so the SW was expected to compensate and that was almost impossible with any degree of succcess. They'd hobble through a CD painfully, but put on a scratched disc or one with defects and all bets were off. Thats what a $15 CD player gets you. And do not even get me started on "1-bit bitstream DAC" rubbish.
Then there is the cost reduction on CDs themselves. Old CDs were nice thick well pressed affairs made of quality layers. They has a nice satisfying gap between songs (incidently this allowed the original analogue CD systems to jump from track to track looking for a certain signal from the subcode in the pretrack gap as it skipped across the disc surface - on the datapath/audio was digital in those days).
Last but not lesat is CD cop yprotection that erodes the CIRC scratch protection systems, if I start on that I'll begin ranting - thank god thats dying a death.
When I get a CD these days, when it is shiny and new I rip it, MP3 it, and then put it on the shelf where I look at it wistfully. I'm afraid, I'll scratch it and rended it paperweight.
And you're a self-righteous dickhead. See, I can name-call too! I never said I didn't enjoy the portability and convenience of MP3 players and the like. I simply appreciate what DVD-Audio technology can deliver (that being, high audio fidelity and immersion). I never claimed to be better than anyone else because of it. The equipment I use doesn't even approach the $500 mark in total, and consumers at large seem to have no problem doling out that kind of cash for a fancy iPod. My statement seems pretty valid that the majority of consumers don't care about audio fidelity. I guess you just can't be bothered to use your brain, you'd rather swing your internet cock around in an attempt to feel good about yourself.
If the expansion of the HD disc markets ever reach into the music industry, will Musicians be expected to write 100+ songs to consider it viable to produce an Album on, say, Blu-Ray?

For a "CD replacement FD" @ 1gig they are like 5.99 @ newegg. Yeah it's more expensive than a CD. It's also easier to tote around, and in the same format, and size package, you can get 16 gigers! (I just found out today, that those things have come down to reasonable to me levels)
How much is your data worth? Back it up now.
For what they are, CDs are still pretty good, but only having 80 minute capacity is something I've felt has always been a limiting factor. CD players that supported data CDs loaded with MP3s always seemed like kind of a hack to me. In the meantime, I've discovered compression formats like AAC+; perhaps it would be a good idea to update the current uncompressed format of audio CDs to include optional AAC+ (or other high-quality, low- or no-loss) compression? Seems to me like a good trade-off between sound quality and the ability to stuff a standard 700MiB CD with 12+ hours of music. Otherwise? I haven't regularly used audio CDs on a regular basis for much of anything. I'm either using an MP3 player or some digital format stored on a hard disk -- or listening to Shoutcast, as I am right this moment. That being said though when I want to purchase music, I'm more likely to go purchase a physical CD instead of purchasing a download, mainly because most downloadable formats are in MP3, not AAC/AAC+ or better (I don't like or use iTunes).
I'm gonna guess that at least some portion of Macbook Air users probably plugin a USB or Firewire DVD drive. DVD drives (which of course, still read and if the drive is a burner, record, CDs) certainly still have a place in modern computing - watching movies, backups, OS reload.
I stopped my research a year or so ago when all the USB stereos were craptastic, and expensive. It seems that now, there are far better options out. Looking at A crutchfield, I think they have over 60 ones w/ usb input now!

How much is your data worth? Back it up now.
the problems with sacd are more a case that to achive the maximal quality you must capture and edit the audio data as a bitstream. Audio editing software is designed to work on PCM data and most A/D converters output PCM.
Yeah, because I'm always running over my music collection with a truck.
Want longevity? How about the ability to quickly rip a perfect digital copy and make as many backups as you like? I think that's a pretty good idea.
I don't know about you, but my CDs ARE backups. And they're safely stored in my closet. Unlike my tapes, which I threw away, after they wore out from use.
Go buy a book on basic information theory. The Nyquist theorem states that if your sampling rate is at least twice the highest frequency, the reconstructed waveform is indistinguisable from the original.
Now, in edge cases CD can fall flat, because 22KHz may not be enough to capture the full sound. While 22KHz is beyond the limit of most humans' hearing, it is considered good enough, but sometimes high harmonics do have an influence on lower harmonics, and the standard low-pass filter that cuts off a CD at 22KHz will kill those high harmonics and their side-effects. But that's admittedly an edge case. I'd wager that CD is good enough for at least 99% of all music.

It's interesting to not that everyone thought I was Dead serious w/ my analogies. I am never serious. but I do think that CDs are about done.
There will be a breakthrough new way for digital distribution of music. Many schemes are going on right now. CD's won't be around forever. But just to note, I saw VHS tapes for sale the other day. Who here has watched a movie on VHS in the last 3 years? Not too many I'd guess. CD quality MP3's will only grow in popularity. Most slashdotters use EAC http://www.exactaudiocopy.de/ (or a comprable program) to rip their music from CD's they own anyway right?
It's allready happening. Cell phones. Yeah Verizon is trying too hard to make money on what could have been an easy way for them to STEAL cash from the public, but they priced songs too high, and chopped the bitrate (WAY) too low. If they pulled their heads out of their butts, and fix TWO small problems, BAM! a real i-tunes competitor w/ a decent install base of allready capable phones, and a solid network to distribute w/.
I think it's kind of amusing that I have been able to watch full length movies on LG phones for 3 years, but we still rely on CD's as a distribution method for Music.
In another post, I wrote about how CD's are not a bad method for the US, our penetration of Broadband is not the best by comparison to other countries, HOWEVER, they are still going the way of the cassette, it's only natural. Maybe not as fast as Cassette gave way to CD, but going none the less here is why:
1. They are bulky compared to new storage media
2. They are not as durable as new storage media
3. They can't be rewritten as much as new storage media
4. Their are limited to 650mb.
5. The general population wants the portability & compatability of a file, and the ability to buy by the song.
It's odd, the general crowd agrees w/ these things but thinks that CDs will stick around forever?

DVDs allow for a higher sampling rates, so less sound is lost. The sound, as a result, is more true to the original source. Currently, DVD movies use 96,000 samples per second or higher.
In theory a 96khz sampling rate ADC should be superior to 44.1 because it allows the anti-aliasing filter rolloff to be shifted above the range of human hearing, creating a flatter passband. In practice all modern sigma-delta DACs use oversampling, 128x, 256x, whatever the case may be. Not only does this reduce the complexity of the input analog anti-aliasing filter, but it pretty much ensures that even at a 44.1khz sampling rate the passband is essentially flat out past 20khz.
I think the issue you have with "slow output" may have less to do with the sampling rate and more to do with the slew rate of the analog amplifiers and overall design of the DAC - on consumer equipment cost cutting measures have to be made somewhere, and the analog output circuitry is often where it happens. Op-amps with very fast slew rates and ultra-low noise, like the Burr Brown OPA series are far too expensive to use in consumer grade equipment.

What is "true to the original source"? If a difference can be heard at a 96khz sampling rate, then the recording has to be made on absolutely top quality recording equipment in a pristine acoustic environment. For recording jazz and classical this may make sense - but for most other genres including pop and rock the "original source" material (guitars, synths, drums etc.) have very little sonic information aside from noise above 12khz or so anyhow, and before being mastered at 96khz have probably been run through dozens or hundreds of bog-standard ICs in mixing consoles, dynamics processors, and effects. In that case it's hard to justify the sonic advantage of the last step in the chain being "true to the original source" when the sound of the original source has already been processed beyond recognition.
Why can't CD players play through a skip? Given the ability to put logic in the players, it's incredible that a player can't understand that it is skipping.

Vinyl audio has less information content than CD audio. The frequency content is approximately the same between the two, but the dynamic range in vinyl recordings is less (about 75 dB v. 96 dB).
Er, no. It's all about frequency content. Whether events in a musical piece occur at 10 Hz or 3 Hz, a sample rate in the multi-kilohertz range will have no problem picking them up. The signal in between the samples is perfectly reconstructable up to frequencies of half the sample rate.
When audiophiles prefer vinyl it's because the sound is different, not because the fidelity is higher. There certainly are elements in the processing chain that could hurt CD audio -- such as the steep anti-aliasing filters needed to kill aliasing while preserving as much of the frequency range as possible -- but vinyl audio processing also has its drawbacks. Just say, "I like vinyl better," and leave it that. CD audio is not inherently inferior.
Er, no. It's all about frequency content. Whether events in a musical piece occur at 10 Hz or 3 Hz, a sample rate in the multi-kilohertz range will have no problem picking them up. The signal in between the samples is perfectly reconstructable up to frequencies of half the sample rate.
An interesting detail is that Shannon's sampling theorem has a bit of fine print: that a signal sampled at twice its highest frequency is perfectly reconstructable provided that the bit depth is infinite. This makes intuitive sense; the minimum AC voltage level change that is detectable by an n bit ADC is V/2^(n-1), where V is the maximum RMS voltage swing. So for a 16 bit ADC with a 2 volt RMS input that's 60 microvolts. In an ideal ADC signal level changes that are less than 1/2 that amount are going to be quantized down, and vice versa for above. Since you can divide an analog signal into an infinite number of divisions it follows that you'd need measurements of infinite precision to capture the signal with "perfect" resolution. Of course in practice even with a 16 bit converter those levels are probably well into the noise floor - but mathematically it truly is impossible to digitize a signal and then reproduce it perfectly.
Apple does everything first.
As long as you don't consider computers not made by Apple.
Can't resist another chance to further display the sad state of your mental faculties, huh? It's hardly my problem if you can't wrap your brain around the relevancy.
I still have the historic Sony D-50 (nice picture here) my father bought for me in 1984. It was called portable but it ran on AC power only. However it was astounding back then how you could make a CD player that small. I don't use it but it still works fine. A jewel of elegance and function in electronics.
Music CD's DO support metadata, and have since 1996: CD-Text.
http://en.wikipedia.org/wiki/Cd_text
"CD-Text is an extension of the Red Book Compact Disc specifications standard for audio CDs. It allows for storage of additional information (e.g. album name, song name, and artist) on a standards-compliant audio CD. The information is stored either in the lead-in area of the CD, where there is roughly five kilobytes of space available, or in the Subchannels R to W on the disc, which can store about 31 megabytes. "
I remember seeing support for CD-Text on car CD changers almost 10 years ago, and most non-cheapo CD players these days support it if they have room for text on their display. But CD-Text never seemed to catch on for some reason. Maybe because the record companies never bothered to add the data to their pre-recorded CD's. Or that a lot of CD player displays only consist of Track Number and Play Time, so there's no way to display text.
Most burning programs like Nero, and even iTunes, support both burning CD-Text and reading it from discs that have it, so you can add it to your own CD's if you feel like it...or if you even bother burning music CD's these days.

""This sorry piece of crap is proof positive of American stupidity"
Stupidity? Despite it's larger size, 8 track caught on for what were then good reasons. For one, you're understating the sound quality issues with early cassettes. They were crap for sound quality, and and early cassette players were notorious for unreliability.
By the time cassettes caught up in terms of reliability and quality, there was a huge market of existing 8 track tapes and players, and for its time, people were fine with them. You sound like Sony, berating "Stupid Americans" for not switching to the "obviously superior" Beta standard. And you're just as wrong as they are for the same reasons; why should we have gone out and spent millions of dollars to replace what was then a satisfactory standard? 8 track had everything we wanted at the time.
Look, I hated 8 tracks, because you couldn't fast forward or reverse very well (I liked LP's the best as a kid, because if you wanted to fast forward or reverse, you got up and moved the needle... voila). But it wasn't American Stupidity because consumers wanted the quality of reel-to-reel tape in a portable setting without the hassle and mess of reel to reel. 8 track gave them that. Cassettes initially did not.

It's too bad we can't get ourselves something like this but for movies.
For some reason "the industry" is fine giving away its music, but movies?!?!? NO WAY!!! (and yes I know nothing was really done after DVD was cracked in a month or so's span, but upscalers seem to only do 1080p with hdmi, and bluray only does 1080p with hdmi, I don't even know if it does component)
It's too bad Toshiba/DVD Forum couldn't "donate" the HD DVD specs. It would have made it useful for people wanting to make their own movies and archive them. Sure, not many people could play them, but can't all HDDVDs be played in normal DVD players? And of course a close-to DRM-free format would be a big hit.
No, you're wrong.
Asus eee 700 series didn't have optical drivers, neither did its sucessors. (I don't know about thinkpad X series) XO-1 didn't. Classmate PC didn't.
Oh, and Compaq Armada and such 90's cd-less laptops.
Asus is hardly a small player. They were the biggest name in motherboards just a few years ago, and they're still by far #2, behind Gigabyte.
Apple is hardly the first to drop the optical drive. And the macbook air is the most terrible notebook I've ever seen. It's thin. Wow. Now find me a laptop bag for it. Yeah, not exactly thin, and can't exactly fold it.
I'll take a 299$ Dell e, or a 499$ HP 2133, even if it's a half-inch thicker.
Yeah, the CD is healthy. That must explain the drop-off rate of CD sales last year, 20% according to some estimates. The record is actually seeing a revival, as no digital format, due to its nature, can create a continuous sound wave like a record. It's only attraction was volume and portability, both of which were surpassed by mp3's. You can get the same or better sound quality on an mp3, as well; and with the storage space of these players rising, you can fit a high volume of 256k mp3's.
Between the resurgence of clarity in LP's for the audiophile, and the quality and portability of mp3's, you can write off cd's in about 5 years.
Adjusted for inflation, that is over $600 now. You can certainly buy one now for that money that sounds better than yours, just don't expect a $25 K-Mart special or even a $100 Sony to do so.
If it works and sounds good, don't replace it. But if you must, rest assured that you can buy one that sounds as good or better.
And yes, most DVD players suck ass in the role of CD player.
OK, here's a CD. Think it has a bright future? Let's find out. Hmm... just pop it in, close the door... TIME-0-0-3-START... POW! Hey, it really did have a bright future. Short, but bright.
You're trolling, right? Please tell me you're trolling. You do understand that the only information lost at 44,100 samples per second is well above 20kHz, the conventional limit of human hearing. And that most speakers aren't going to be reproducing those frequencies accurately in any case. And that the pace of the music has nothing to do with it.
I'm pretty sure you're trolling... but you could be one of those audiophiles who believes in the sound-enhancing power of pure silver power cables...
This whole article was a troll, right? CD's are deddy deddy dead dead dead. But we all knew that already.
I am pretty sure that we have (maybe) one generation of optical disc technology to go before solid-state technology overwhelms it. Data will be transferred over the network or with small solid-state storage devices (MicroSD?).
"Nowadays CD has been replaced in some segments, but not on the music industry, that continues to support it massively."
I haven't seen a disc with the compact disc digital audio logo for sale in a music store for years.
The music industry abandoned this particular standard years ago, as it doesn't support DRM. It's been supplanted by something that may or may not play on a legitimate player of compact discs (the publisher makes no guarantees), but will fuck up your Windows or OS/X installation regardless.
I can buy CDs cheaper than buying via a legit download site. And there is no problem with buying and selling used CDs on eBay/Amazon. Until that changes, CDs are certainly not dead.
