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.

I've actually considered trying to research finding equipment to manufacture such media, and/or recreating it. Everyone needs another hobby, right? That said, in my day job, I've seen IT folks at times be their worst enemy in focusing so much energy in keeping outdated items running, only to discover a lack of support to upgrade/replace said items because they've removed the friction of staying with the outdated device/system. Part of me sees the same issue here. It'd be expensive but not insurmountable to recreate lots of media options, and even more realistic if some of the old manufacturing equipment is still mothballed and not scrapped. But, putting new floppy disk media into the market, even at inflated prices, would remove the friction IT resources have depended on to force governments and businesses to at least migrate to solid state replacements, if not fully upgraded systems. Obviously, the cost (and the fact that finding existing equipment to un-mothball is the much more realistic an option to pursue rather than trying to fabricate new equipment) is a significant roadblock, but I also hesitate for the above reason. It's almost like a few more years need to pass, to force the remaining holdouts to realize floppydisk.com and eBay and the nature of rust glued onto mylar will not exist much longer at quality levels that companies can risk.

Thats exactly the solution. Just keep a few floppies around so that you can transfer a saved image back to floppy to be read by the machine that needs it. Personally, there was so much media manufactured that I think the machines that read the media will fail long before we run out of media.

Floppydisk.com also sells 100 promotional disks (no working disks) for $12. They also sell 5.25 nonworking ones with different colors that can be used for projects.

There's an old saying that the perfect business to be in is one large enough for one vendor, too small for two. It certainly would be conceivable for somoene to buy up the business when the current owner retires, if there's reason to believe there is enough revenue to keep one or two people happy. It's no different from the thousands or perhaps millions of small manufacturing businesses. Curiously enough, some of these close down when the owner retires without an apparent effort to find a buyer -- I remember a local tote bag company, or for that matter the much lamented Lindsay Publications. For a nice example of a small business in our subject area, consider Ersatz-11. paul

Sounds like that would be good for hundreds of disks. I've mentioned it multiple times on VCF and it's also mentioned on Herb Johnson's retrocomputing web site. I can't risk clobbering a client's disk or tape, particularly not one sent by an institution's achivist of whom I'd like to remain on the good side. D5/Cyclo has been a lifesaver. The stuff is slick but inert; it's used extensively in cosmetics and lotions. It's also somewhat volatile, so it evaporates after awhile. Hair detangler is a very notable use of it that even finds use in equine circles. I suspect that you could drink the stuff and not suffer anything but a bad stomach ache, but I'm not about to prove it. Another bottle of stuff that I keep around for softening rubber pinch rollers and capstans is methyl salicylate/oil of wintergreen. Smells to high heaven like arthritis cream. Mixed with a mild solvent (e.g. xylene) it softens hard rubber up quite nicely, but your shop smells like a gym locker room for a time. And of course, heptane for cleaning--dissolves glue, cleans tape heads, etc. without harming plastics or staining paper. FWIW, Chuck

Maybe a dumb question but would an easy bake oven be a good device or are they not good at holding temp control?

No--you really need good temperature control for two reasons (at least in my experience): 1. Magnetic media on a mylar substrate doesn't have much thermal inertia, unlike a PCB. So when the temperature goes way above set point, it can do damage. Recall that you're working with plastics. 2. You're walking a fine line on temperature. Much higher, and the medium could be damaged, but too low and baking does little good. Check with the tapeheads people--the audio tape fraternity does a lot of this sort of thing. --Chuck

Yes, for example you can get an oven controller from Dbit (John Wilson, author of Ersatz-11) to do that. I remember an article in a German ham radio magazine that discusses the subject, and points out that it's trickier than you might think. The reason is that toaster ovens are basically IR heaters, so the temperature of the object depends on how much it absorbs. In the article there was a suggestion to attach the thermistor used by the controller to a second PCB similar to the one being reflowed, so it would sense a temperature close to that of the real board. paul
