In my less ethical and more introspective moments I'd always wondered how I
could make a disk good and unreadable by anyone but myself. I played around
with unusual angular velocities and sub-normal GCR checksums on the 64 and
came up with a double key: both on the drive and the system. A device like
Teledisk, even if it could read GCR, probably wouldn't work for duplicating
such formats. The problem is that using something like angular velcotiy would
be keyed to a particular drive's characteristics and that would be the first
thing they'd confiscate.
