 The cd players you are referring to are pretty complex devices. Among other
 things, most will extrapolate "frames" to compensate for dropouts, using the
 information in the bracketing "good" frames.
 This is necessary because dropouts/misreads/etc are relatively frequent. It
 works fine, too, because your eyes or your ears won't be miffed by occasional
 inconsistencies.
 But this won't do for object files and databases.  

 Eventually, what you are proposing will likely come to pass, albeit in more   
 expensive form; there are a lot of people working in this area. A few compa-
 nies have pre-announced cd drives for pc's - all substantially more expensive
 (and with a fraction of the capacity) of their audio/video brethren - where
 write capabilities are included. Storage Technology aside.
