I wonder how much challenge would be involved in making artisan batches
of
5.25" or 8" floppy disks using
cobbled-together or homemade equipment?
Is there ANYTHING besides floppy disks that uses large areas/sheets of
magnetic material?
Is there ANYTHING besides floppy disks that uses a liquid magnetic media
that could be used for the coating, and might even be available, or would
that also need to be bespoke manufactured?
How precisely does the coating need to be put down?
It certainly doesn't seem like a reasonable, PRACTICAL project. But we
tend not to BE reasonable and practical.

Reasonable? Are you serious? We run decades, even half century old
computing machines in our garages for fun.
I would've suggested the manufacturers of debit/credit cards as a source
for the magnetic material but that seems to be giving way to the chips.
But I'll be willing to bet a supplier could be found on Ali Baba for some
sort of magnetic thin film material. It would be cheating, but floppy
disks won't be re-invented in a day.
Ultimately, it would be fun to actually mix up the magnetic paste and apply
it to a flexible mylar disc with a centrifuge. It would definitely be an
adventure. And a very unreasonable one at that.
