A while ago, I posted an article in another newsgroup asking about the
memory capacity of laser disk. Currently, laser disks used by computers
typically have a few hundred Meg bytes. However, according to my
computation, if a laser disk stores uncompressed digitalized pictures,
its memory capacity has to be much higher (consider a 90-minute movie.
it needs to store 25x60x90 pictures). Does anyone know the mechanism
of storing pictures in video disk?
