Yamaha CD-RW Drive Writes Images In Substrate 304
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"

Alternatively it is very good software that merges an image on top of data that is acceptable to a normal CD writer.

1) Mass produced CDs are pressed, not burned. So I don't even know if this process will work for a pressed CD which uses a different authoring process.
2) Even if this was possibile in that regard. Having a unique CD key pressed onto each CD would result in creating n templates (where n=number of cds pressed) which is too expensive to be useful. This is sorta the same reason as to why we see CD Keys on cd cases, but never printed onto the front label side of the cd.

Not really. All they're doing is taking advantage of the fact that a burned part of a CD looks noticeably different from a non-burned part, and selectively burning.

Let's do some math: CD players turn at 1.2-1.4 m/s Constant Angular Velocity [umn.edu]. To get 250 dpi at that speed (1X), each dot is 78 uSec, or about 12,800 dots/second. Gigabit speeds are literally a million times faster.
I'm not so sure that the laser is actually burning through the reflective backing, though - it looks like the pattern is only visible on the underside data area - just like you can see the difference between burnt and unburnt data.

Traditional CD's (like when used for music) are constant linear velocity. CDROM players vary, but can be constant angular velocity - this means that they don't have to change speed of the disc when accessing different areas (which takes some time to do), but also means that the linear speed (proportional to data transfer rate) varies between the inside and outside. That's why drives are labeled as "max ##x" - that's the transfer rate at the outside; at the same CAV, the transfer rate will be less at the inner grooves.
I was just going for a ballpark number, so it's still a good estimate. As a side note, I'm not so sure that this could have been done purely in software with a traditional drive.
First, there's the position synchronization issue -- there's no way to reference what angle of the CD you're writing to. And since CDs vary in their pitch, either intentionally (the main difference between 74 and 80 minute CDs) and accidently, you couldn't reliably precalculate where along the linear track to burn.
The other issue is actual control of the laser. Since recording is done by varying the pit lengths (or something like that), there is always a burn mark and the the only variation that your data causes to this is at a microscopic level.

Do not underestimate the 'gimmick marketing potential' of this idea. Let me explain:
I'm not talking about marketing this actual Yamaha drive. I am talking about using graphic-ized CDs as marketing tools in themselves to sell other products.
If a company wants to sell something and have their marketing materials stand out, the marketing materials must have some sort of neat quirk. This can be in the form of a keychain with a built in puzzle, those business card shaped CDs, or whatever. They're neat things. The first time I got a business card shaped CD (marketing from MSFT no less) I did not believe when someone told me it was a real disc so I put it in my machine, and played the marketing video on the CD. Lo and behold it worked. And I ended up watching their marketing video.

One of the things I want to do is burn a CD of all my Lightwave projects. It'd be cool if the burner software was smart enough to get all the folder names and burn those into the disk.
In other words, I could burn and forget instead of trying to decypher my handwriting later.

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.

While probably not quite as hard, it's on the same order of difficulty as writing a poem who's MD5 checksum is the first 32 characters of the declaration of independence.
First off, the CD-R writes pits whose edges are detected, so you have to translate edges into pixels.
Also, you'd be limited to pits/lands that are between 2 and 10 bits long (if memory serves), since the data you feed it are eight-to-fourteen modulated (eight bit data coming in are translated to the set of fourteen bit numbers with strings of 2 to 10 zeroes -- note that there are a few extra suitable 14-bit values, which is where the subchannels (p, q, etc.) come from).
But before you do that, the CD-R interlaces the data around the disc so that a scratch won't wipe out more than a few bits of a given byte. So you'd have to figure out in advance where a given bit will end up.
So it is probably theoretically possible to burn a certain set of images onto a CD-R. If you pull this off, you might send a copy to the NSA and maybe they will hire you.
