- Please, anyone correct me if I am wrong, but as I understand it, even if
- the new recordable (MD) technology used CD-sized disks, it would still have
- to use data compression. The writing technology requires a lower bit-rate,
- which is possible when using compression. If compression were not used, the
- bits would be coming in too fast for magneto-optical process to handle.
-
- Does anyone know the real story here? As far as I know, this is the real
- reason for compression, and making the discs smaller is possible as a side
- effect.
