In my humble opinion, what's really needed is a
quick and
reliable non-contact method of recovering floppy data. Perhaps
one of the more modern head technologies, such as GMR might be
suitable for a head that doesn't contact the media.
Would a non-contact head
'fly' properly at floppy speeds, though?
(I'm not sure how much more rotational speed you could get out of
a floppy, even jacketless - I suspect the media is just too flexible)
I keep wondering if the disk media could be "mounted" like a
specimen on a slide. Then a flying head wouldn't be an issue, and
multiple passes become possible.
