	CD roms will be capable of storing 2-3 orders of magnitude more
data/area. The traditional density limitations don't apply to laser.
Theoretically, you could build a drive that is diffraction limited.
Grollier's is going to be manufacturing a CD encyclopedia. Perhaps
this will give you an idea of how much one of these can store. The most
practical application is for reference databases.
