- Hello,
-
- I wrote an OS/2 device driver for Sony CDU-31a.
-
- CDRoms can only be written using a special drive transport for that
- purpose. These transports are available ranging in cost from
- about $750 to $2200 depending on how fancy you want.
-
- CDRom drives that come bundled with sound cards are only readers.
-
- Regarding reading the tracks, requires a device driver. If you are just
- interested in reading raw data, then you will have to
- (sign a non-disclosure agreement) get the technical specifications
- from the CDRom manufacturer. The only way they will give you that
- information is if you tell them that you are writing a device driver for
- some operating system. Make sure the drive you plan to write for,
- has the same version level embedded software as the relevant
- specifications.
-
- It is my opionion if you are just interested in the topic, for you to
- get source code to the Linux operating system and review the
- CDRom device drivers source. That will give you a very good
- beginning on the topic and at the same time demonstrate
- how 'real' code works.
-
- If you are interested in CDRom track standard then you
- will have to acquire a copy of the Philips 'Green Book'
- specifications.
-
- This book is one of a series, and they cost around
- $15,000 dollars each. It is intended for manufacturers
- only. Who else can afford them?
-
- I do have excerpts from the Green Book, but it really
- is of little interest to hobbyiest programmers.
-
- Good Luck,
