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!"
...except mp3s...

I mod down every jackass who puts his moderation policy in his sig. Oh, wait a sec....
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.
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?
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.

I bet there is some occasional unexplained knee pain. And for some reason, compact disks can no longer eat bananas without violent diarrhea.
Unfortunately we can't sing Happy Birthday to the CD without paying royalties. Such a cruel world. =/

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?

The iPod spells doom for the pop music CD. All the other music genres are doing fine on CD.
And if you listen to the RIAA, then the sole reason for that is online piracy. They always point to that peak in the 1990's as being the point that CD sales should be at (or higher) if piracy was stopped. However, it is more truthful to say that it was a temporary high point in sales and that sales dropped afterwords due to normal market forces. (Normal Market Forces including piracy, but not as the main component... probably not even as a major component.)
My sci-fi novel, Ghost Thief, is now available from Amazon.com.
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.

rediculous.
You can't buy online music from a band at 1:30 am inside a bar as you drunkenly stagger and give them the ultimate praise: "You dudes rock!" But you can reach into your pocket and pull out a $10 bill (you've been doing that all night anyway as you buy beers) in exchange for a plastic box.
CDs aren't going away yet. They, combined with T-shirts, are an important part of offsetting some bands' travel (and drinking) expenses. How can you replace that? Bring a laptop along on a night of drinking, and hope the bar has free wifi, so you can say "you dudes rock" as you peer at a little screen and give them the satisfaction of seeing you click on something, so that the band can then collect the money after they've already spent it on beer and gasoline? I don't think so.

As soon as 'the kids' can transfer music phone 2 phone there goes the music biz.
That can be done now in countries where phones don't routinely have their Bluetooth crippled.
O frabjous day! Callooh! Callay!
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.

Digital download cards. My band is planning to release our next EP entirely digitally. Because of this need to sell a physical product at shows, we will be selling digital download cards (like gift cards) to buy the music from our site.
The new fan receives something tangible and the benefit of full album artwork. The band gets cash in their hands on the spot with a decreased cost of physical overhead.
Everybody
Steal my band's record! Seriously,
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.
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.
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.
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.
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.
Apple does everything first.
As long as you don't consider computers not made by Apple.
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.
