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.
