Remeber you'd have to make some changes to the
tracking servo to allow the
computer to go to a particular block on the disk.
I was thinking of simply reading the whole disk, as if you were going to
transfer its contents onto a more modern media. If it does get to the
point that CD-ROM drives in working condition are indeed rare things, it
is time to move to another format.
Now that CD players are becoming cheap, it's
getting increasingly hard to
get real service data on them. And that's what you'd need to modify one
into a CD-ROM drive.
The servo systems in those things are dead stupid, and should not really
cause many problems reverse engineering those bits.
