The unfortunate thing about optical disks is at the single bit level,
they are pretty unreliable. Typically, 20-30% of the disk is used for
error detection and correction. I understand that the NeXT machine
uses about 30%. This wastes a lot of space, but make the disk very
relaible. More than likely, no one else is doing quite the same thing.

Not true. The optical media for most 5 1/4" WORM drives (eg ISI, Optotech,
etc.) runs over $100 dollars, and often lists for $200. $50 is pretty
reasonable by comparison...

Perhaps, perhaps not. Remeber, an optical disk is not subject to
head crashes and other magnetic disk problems, so you don't have
to worry about the power going out and thrashing your data. That
is not to say that I won't buy a second drive, but it will be for
speed, not data reliability...
