Hi! We're all using CDs of different kind (CDs containing data, audio CDs, maybe even some with more interesting formats like those for some old arcade games using the 30 MB of R..W subchannel information, ...) I'm currently trying to gather as much information about the low-level format of CDs as possible. While there's a lot at a first glance, it's all mostly unuseable. Eg. the SCSI MMC-3 draft tells you how to get some of the "interesting" data, but there's of course no reference how to decode the data. I've been looking for the "Rainbow Books" (Red Book describing Audio CDs, ...), but those are quite expensive. Partial information is available through standards of other kind (eg. most of the Red Book became an IEC standard, too), but those are a bit expensive, too. Did you ever come along detailed technical documentation about these little silver beasts that'd allow to hack some nice extraction and refactoring tools? Or do you happen to own one of the books and are willing to hand it over to me for a week?
