It's very, very common for double-density CP/M
disks to have the boot
sector - and in some cases the first few tracks - in single density.
Broderbund came out with an 18-sector format for the Apple ][, but in
order for the disk to be readble the first track is encoded as standard
16-sector format.
This 18-sector format provided two benefits: 1) increased storage space
and 2) a form of copy protection.
For these odd formats, I just record the waveform from
the head
for each track for a couple of revolutions, just to make real
sure that I'm not missing anything :-).
What do you record it to? I don't think this is a very good solution for
mass archiving and distribution.
