Yamaha CD-RW Drive Writes Images In Substrate
johnny5 writes: "Yamaha has recently demonstrated a new CD-RW drive that can write images into the unused space on a CD-R disc after the data track is written. The technology, called DiscT@2(TM), is due out in Japan in July. The images print on to the CD at approximately 250dpi, making graphics as well as text possible. More info can be found at Yamaha's CD-RW site (in English) as well as at Akiba PC Hotline (in Japanese, with better pictures. Babelfish for suitably akward translation). No word on a timeframe for U.S. availability"

What are the security implications of this?!
How about burning in something like 'Fuck you RIAA' onto every CD-R. That'd make them happy.
wouldn't it make more sense to develop better and faster optical media storage than to waste time creating a burner that will write images onto your cds? i guess this has some 'wow cool' value, but other than that i don't see what the point is.
For anyone wondering what the word 'hack' actually means, THIS IS IT.

Any information on availability? This is a feature I would want to pay money for. Getting those CD-labels looking right is always a pain.
And these embedded pictures look cool too...

Maybe I'm missing something, but Why is it the drive itself that is important? I would think most CDs are pretty much the same (correct me if I'm wrong), so after doing a bit of math, properly enhanced CD-burning software should be able to do this, right? Well, maybe not, I never claimed to be a genius.
So not only can we make pirated CD's, we can now put copy protected images on them as well... you probably can't see it, but I'm doing a little dance for joy over here, knowing that I can piss off the RIAA even more

For smaller companies, now that is a different matter and something likw that would be rather neat and useful.
Plus, isn't the market moving more and more towards DVD burners? I have a 4x CD burner at the moment and when I upgrade i'll be looking more and more at a hybrid CDR/RW/DVD combination job and not a 32x CDRW with the ability to burn pictures on it.

Wanking while watching pr0n CD's just took another dimension.
is there any actual use for this? Id rather buy a drive that burns faster than one that prints images on my CDs. That thing must cost lots of money, and its not a actual new feature, I already saw some presentation CDs here in the company I work for with text printed but I believe those were done with MUCH professional (expensive) equipment.

I was doing that 10 years ago with optical cards. You could print an image on the optical surface in a similar way as the CD-RW. Of course, you couldn't put any data on there...and the writers/readers cost $10k each...and they were SCSI only...

How long 'till this hack, or a similar one will be available for any CD writer? It's an incredible idea - I love it - but it can't be that hard, can it? Just a matter of finding out a where which bit goes and then writing a descent piece of (open source) software, right?!?
Let's go!
What about this idea... make the software work such that you could use all that unused space on toasted CDs. I have loads that crapped out after just a few meg, thus the crap track is only a tiny width, and there's lots of real estate left for pictures. Now THAT I might use!
Unless I'm misreading this, the image only appears on the data side of the disc. And the last time I looked, even on a bare no-label CD, I couldn't see where the data ended from the label side.
I don't know about you, but I'd never label the data

Yes. But I couldn't justify the expense JUST for doing that, but that's the first /practical/ use I've read yet. CD clocks would look uber-l33t with graphics burned into them... but for added hack value, why not just put together something like a GIF2ISO... er, I mean PGN2ISO program so everyone can do it for free?
Problem solved, no need for a usable CD, it's just artwork =) No extra cost, just grab the free program.
Yamaha worked on their quality control. My Yamaha burned stopped working just outside the (12 months) guarantee period, and so i`ll have to buy a new one, as no-one fixes this stuff.

It would be cooler if someone would design a disk that could display a picture in the area where data is stored (perhaps store data on a lower level, like on double-density DVDs) so you could have art on the underside of a full-length album.
Frankly I think all of this is a little bit cheesy, and while cool every once in a while, would get old fast if put into general use.
In Capitalist America, bank robs you!
What would go along well with this is double sided CD-R disks. I've always wondered why they aren't around. Have one side completely free to write these pretty graphics, text, warez keys, and the other side for the data or music.
Sometimes, you might use a CDR for something other than just data storage. Distribution of your own demos, for example.
;-) you might just want to make it look a bit less dull.
On any occasion where you have a little space left on your CD (and a little time in your tight agenda
I am sure I have heard of someone doing this before in software, but I can't find a link. It should be quite simple to do if you know bit widths and track diameters I guess. As long as Yamaha haven't patented it I can see this turning up as a plug in for CD writer software quite quickly.
This will probably start turning up on ISO's soon, and it would be cool to have a nice Debian mini-CD ISO hacked to say "Woody" in the unused space! Of course, now we have the possible pain of ISO adverts...
I mean, when you put it in a drive you can't even see it, and if you could, it would be spinning too fast anyway. When you remove it from your drive, you better put it to the case if you are going to use it again, so you can't watch it then either.
neat, but totally useless..
Software should be free as in speech, but if we also get some free beer, all the better.
Why didn't they design a cd-r that would simultaenously print the label on the top of the cd? Who cares about the bottom?
I think that marketing deps just looked into numbers and figured that 90% of all CDR made by teenagers (mainly porn, divx and warez stuff)

So they named new technology according to their target group preferences.

I know becuase I did a lot of research on this. I went to Best Buy and talked to their knowledgable staff and they told me this was the thing we needed.

They also told be I should buy the extended warranty contract, so of course I did- you never know when some "new technology" is going to break and you won't be able to fix it.

Maximum PC Magazine had this information like last month. And I cant find the link but I think Tom's Hardware had information as well.
Most of the people I've been around in the last six years have moved to using things besides floppies. Most have used Zip or CD-R/CD-RW media. Part of this could be that I'm mostly around more computer literate people. I graduated from college in 1998 and even then, Zip disks were pretty popular.
I'd be surprised if many people really use floppies anymore, but I'm pretty out of touch with society.
Don't fall for this. It's just a ploy to get us to buy more CD-RWs to feed our artistic habits. :)
Now that I think of it, an intesting art display might be a wall full of these making up a complete picture. Might have to find a bunch of those ractangle CD-RWs tho. Are those even produced? Ah, nevermind.

Actually, why bother recording data at all? Just MIME-encode the data you want to store, write it to the disc as graphics, then scan it back in, and OCR it when you want to access the data

The one thing lacking has been the ability to cross-modulate the burning of a track to emulate Sony's copy protection.
Looks like this drive can do it.
All that is required now is software that will allow you to control the burn across the ATP section of the disc.

i have a lacie (sony mechanism) that i got for xmas 1996...granted it's only 2x and won't write DAO, but the sucker's probably burnt at least two discs a day for over five years, and it still works just as well as the day i bought it. even without a fan (that died about a year ago). not the fastest or prettiest writer, but DAMN reliable.

Facts do not cease to exist because they are ignored. - Aldous Huxley
Actually, that'd be fun to just have a few of those, IMO. Since cd-rs usually have rebates now, you end up paying practicially nothing ($1.34 I think if 5% of $20 is $1 and stamps are $0.34). But any-how, the chance of me getting one of those is in the slim-to-none range.
There's a drawback to its feature. You'll need cd-r/rw with dark blue colored dye to be ale to see images/texts better... light green, silver and gold cd-r/rw are no good. Thus, yamaha website uses very dark blue colored dye disc.
There's an old story circulating among my geekier friends about someone who figured out how to do this with disk packs while working as a third shift a systems operator. Disk packs used to fail at a fairly high rate and it was not possible to tell a good pack from a bad one by looking. This operator figured out how to use the read/write heads to chip sections out of the top platter so that the word DEAD could be read at a glance.

When reading the original writeup it sounded like it was being burnt between the tracks or something - apparently this is not so. It also begs the question of whether this could be done in software with current CD burners...
This is what my little sister has been trying to invent for years...only she used more conventional methods for painting images on CD...
Please correct me if I got my facts wrong.
If you or anyone you know has a green card, work or student visa, check the back side that has the optical data stripe.
Now you know how they do that. This is old tech, but is just now making it to the consumer market.
I just happen to know this because I did a little bit of work on the green card printer system.
For those of you who don't have access to them, they print the images of the first 32 presidents on the back. In uber-DPI, it's not much of a challenge to fit them all. I think there's other stuff too, like your picture. It's one of the many features of the new green cards that helps to discourage forgery.
If, by using this drive, the user can turn the laser on and off at will, it might be possible to record in analogue laserdisc(tm) format on CD-R discs! I know you'd only get 8 minutes of video on them, but that would be cool.
Users would happily pay for copy protected CD's if enough extra features were added to the CD. The copy protection becomes less of a drawback if the number of extra features grows.
So now I can write an image, on the bottom of the CD, in the unused data area. I don't usually make a CD that has a lot of unused data area. Make a CD-RW drive with buit in ink jet printer so I can print my label on top and I'll be impressed. Or (any printer mfgrs. listening) give me printer with some sort of tray that a CD fits in to be printed.
Didn't read it too carefully, but are they using diffraction grating effects to create colours? Or encoding different images at different viewing angles?
If not, anyone else thought about the possibility of doing this?
I've had experience putting images on mastered CD's, so I'll give you some technical facts.
Firstly it is not easy to do through software, although it is technically possible (and has been done already). Basically different CDR's have different track pitch and pit length, which means you'd need some way of calibrating for the media. The pitch and length are the important parameters in determining where a bit in an image will end up on the CD. The further out on the CD the greater the number of bits per rotation, because CD was designed for CLV. So software has to be very precise and know these parameters EXACTLY.
Also, from a software standpoint, the most data you can send down per sector is 2448 bytes RAW. Note that RAW data is not all of what ends up getting written on the disk. There is still C1&C2 error correction that gets written physically on the disk that you cannot control (it is generated by the chipset). The stream also has scrambling applied, and the result is an image that is pretty much correct, but is fuzzy because of the C1&C2 that are out of the control of the software.
The good thing about the Yamaha is it writes in constant angular velocity. This makes it easy to write the image because one line of the bitmap can be applied per rotation. CAV is the way the images are written at mastering. Also, I'd assume that the Yamaha drive is in control of the full stream, so you'll be able to get perfect images because it won't be generating any error data.
One last fact is that images look a LOT better from the top of the CD. This is because the plastic part of the CD is underneath and distorts the reflection when viewed from below. So quite a few companies burn the images in reverse (so they are viewed correctly from above), and only print near the center of the disc. The question is will CDR manufacturers remove the label on top so you get the best effect.
If you have a CDR that has no printing on the top (like cheap blanks), then you can see the image perfectly from above. Of course you must invert the image before burning so it appears the right way.
You can buy a double sided CDR and burn an image on one side and put the data on the other. Here's a link to a merchant selling Sony double sided CDR's: http://www.mycoolgift.com/cdq-13g1.html
There is something similar -- not CDRW, but still interesting enough that i was surprised to find:
take a PS2 DVD (i am assuming it's on all of them -- i personally was looking at FFX) and look on the bottom: you can see playstation logos burned into the disk.
I suppose this uses a similar technology -- but may not be exactly the same, since DVD has multiple layers -- which means that the image can be visible even when there is data there (or at least, on a different layer at the same physical location) -- how many of us are willing to sacrifice half the capacity for purrty images on the bottom of disks, eventually, when this technology comes around for DVDs and whatnot?
My life in the land of the rising sun.
Obligatory complaint: why, this is barely news at all; a very similar story was reported in Slashdot just a few decades ago, in 1961.
The PDP-1 used eight-channel punched paper tape as the predominant storage medium, punching at a speedy 60 characters per second and reading at an ungodly-fast 200 characters per second.
On program tapes, prior to the start of the actual binary program data, the assembler would punch a human-readable label in which the title was spelled out in human-readable format in the block letters made out of patterns of holes. IIRC a 5x7 matrix, a little ugly because a horizontal line of little feed holes ran through the center of the character which meant that not only did the characters look "overstruck," but the spacing between rows 3 and 4 was a little wider than the spacing between other rows.
I wonder what the earliest use of "kludging directly human-readable data into a medium that was intended only to be machine-readable?"
I seem to recall that IBM card decks had a couple of preamble cards in which the punches spelled out a code number in block letters.

My first reaction to this was cool.
My second reaction was cool.
My third reaction was, couldn't something like this be done through changes in existing software?
I suspect this is far more a funtion of software than the burner itself, and hope to see it added as a 'feature' by Ahead -soon-.
I can see the pr0n collectors lined up to buy it.
The DOD should love it, FOU, EYES, etc could be more useful when it's not just on a label that can be pasted over.
For me it's the geek factor.
obviouly, this is designed for writing CD Keys on :)
so if i burn a picture of a felt tip marker slash on the edge can i make an un-protectable cd?;)
have you?
They have the OEM number right on the cd...
That operator's pretty darned smart.
Of course, if he were REALLY smart, he would have saved some time and used a felt-tip pen. Or even better yet, put them in a separate bin for dead disk packs!
The next thing is obviously to put a printer in the drive and print the label side. You can get CD printers, but they cost about $2K and are bulky. There's a thermal transfer CD printer available that fits in a full-height 5.25" drive bay. But so far, there's no low-cost integrated solution.

I'd be impressed if Yamaha could make a CD-RW that could write plain old data without $&%*ing up! After working with HP drives, I can say that the Yamaha CRW2100EZ I bought is a piece of $#!^. Reads fine, but can't write with either an 80-wire IDE cable or with DMA enabled, can't burn at 16x without buffer underrun, vibrates like a table saw at high speed, overheats and goes nuts after burning about 4 disks in a row and needs to cool down for hours before it will work again. Acts the same in two entirely different PCs, one a P4/1.6G w/ASUS mobo, other a TYAN K6-2/550 both with WD 7200rpm/ATA100 HDDs. Yamaha? Not for me!
Have you ever punched a punch card which has a hole in every possible position? It usually gets stuck in the card puncher, much to the annoyance of the sysadmins.
Also, making old hard disks walk across the room by repeatedly seeking across the disk. All good fun!!!
My friend pointed me to one of the pictures, and I remarked about having that idea a while ago with a funky iso on a standard cd writer (Yes, I know it wouldnt actually work) and also that it would be really great if it could burn over the data, so as to be visible to human eyes, but be transparent to a CD laser, so as to allow both data and pretty pictures to be in teh same place.

Can we have the software automatically add the words "This Side Down" to every image so that we don't have to field excessive support calls? I'm not sure how many times I can say, "I'm sorry, but with this CD, the writing goes down..."

I can see this technology as being very useful for double sided DVDs and CDs. It would let you use the whole disk area for a label instead of just the little ring in the center.

Some guy has done it by hand using just scratches in plastic... could a similar system engrave a simple hologram in a CD? Maybe you could have 3d diagrams showing how to insert the thing into a CDROM drive.
"Studies have shown that people who eat peanuts live longer than those who do not eat."
It seems to me that the most obvious use of this technology is to build it into all CDRW drives and require that the drive "Tattoo" it's serial number on to any discs that it burns. I relealize that even if they went to the length of requiring you to "personalize" your CDRW drive, you could still fake it out, it does seeem exactly like the kind of thing content companies might try to mandate (and it wouldn't have any implications viz Red Book compliance)

What I'm excited about is the thought of double-sided CDs. If I can now label (well, sort-of label) one side of a CD while still keeping data on it, I can use that top side for EVEN MORE DATA. This is a very exciting idea.
Why not use that area for writting usefull data in scrapped disks (IE buffer underrun)?

About 1997-1998, one of the many AOL CDs I came across had their logo "recorded" into the disc, all around the perimeter. About 1/4 the disc (inner ring) was used by the bundled software, but the remainder was taken up by 5 or 6 AOL logos, all neatly arranged around the central hole. These were "recorded," not stamped or printed, as upon closer inspection, the edges of the logos had a very fine "blockiness" to them which matched the CD groove pitch. I always wondered if software could be made to do this with a CD burner. What a great hack!

Warning: I know more stuff about CD-R than your mothers, but probably less than Yamaha's genii.
:)
First of all, CD's aren't purely encoded as 0=high and 1=low; they go through a differential encoding process. A '1' corresponds to a transition between low and high, and a '0' means just stay at the same level, just picture an XOR process on the bits. Now there are rules, like having to break long strings of '0' bits to keep the reader from getting confused. You also need to break long strings of '1' bits because they create an up-down-up-down pattern that is also too regular. This stuff is done by the burner itself, by the fabled EFM encoder hated by all CloneCD users
To print these graphics on the disc, Yamaha probably just switches off the EFM and lets their software directly control the laser pulses uncooked. This means you won't be able to do it on just any old burner because even if you did use the proper software, the burner would fudge your graphics in-transit and smooth out the resulting image quite dramatically (remember, readers don't like long valleys).
