Actually, all SA390/400-type drives I've seen (which are nominally limited
to 35 tracks) can step to a 36th track without any difficulties, and
most can go to the 37th. The "36th track" trick was very common on
Apple ]['s, both for copy protection and for general use.

I've noticed that most decent data forensics tools (Anadisk, etc.) will
go the the 81st track on a 80-track drive, though I've never seen a
floppy that actually had data out there.
