The thought of fastening the 'bare' media to something for rigidity had
actually struck me too - but I'd kind of ignored it as:
1) Anything which sits between the media and the head (e.g. a thing film of
something-or-other) is likely to impair read performance,
2) It'd probably be a messy/slow process having to attach media to something
every time.
Then this morning I got to wondering whether a rigid circular plate with tiny
holes in it could be used; the bare media would sit on top of it, and some
process would suck the media onto the plate to keep it in place (possibly
negative pressure somehow brought about by the disk spinning, rather than a
complex pump arrangement).
It'd mean that only one side of the media could be read at once, but maybe
that's an acceptable trade-off.

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. 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)
