- I think MSCDEX hooked INT 25h and 26h so that you can perform disk read or
- write (if the drive is capable) just like on an ordinary hard disk...

-
- I think the original poster meant CD-R for writing and CDROM for reading.
- There already a couple of drives allowing for personal mastering of CDs.

-
- Yes, the technology only allows for writing unto the disc once...

-
- A new session would take about 9MB of space. But I've read in an article
- once that you could create new volumns instead which only take around 300KB
- of overhead (which is much better than 9MB).

-
- Most CD recorders use proprietary software. But more often, the software
- is bundled with the drive when you buy it. I myself am on the lookout for
- any information of how to go about doing a CD writer software. Unfortunately,
- I haven't found any material discussing that nor the drive to test it.
- Maybe next year....
