Yes. I believe a Catweasel controller could be made to do that
sort of thing; it is almost the only thing that can read an Amiga
floppy for similar reasons. Check it out...

I am trying to recover data from some 5.25 inch disks.
They came off an older Apple system. (Apple 2?).
I seem to recall that Apple played some funny games with the
floppies - rather than a constant angular velocity and 18 blocks
on each track inside to outside, they had a drive motor that
could change speeds, so they ran constant *linear* velocity,
got 18 blocks/track on the innermost tracks, and a bit higher
on the middle tracks, and something like 30 blocks/track on the
outermost tracks.
If this is the case, you'll need hardware/software that's capable of
doing the Apple speed tricks....
