It looks like sometime in the future I may need
to rebuild a damaged
magnetic drum. It has some scratches that may be too deep. As a
brainstorm, I am wondering about recoating the surface. If I use
refined iron oxide, what would I use as a fixer (glue)? What was
typically used on early hard disk platters and drums?
Seriously? Do keep us posted... far as I know, it's not something that
anyone's ever tried before - it'd be interesting to know how you get on.
I'm not even sure how you could coat a drum in glue / oxide and get it
of uniform thickness without specialist tooling.
I wonder whether you could mix the oxide with the binder first, and then
have only one uniform thickness layer to apply.
Incidentally, someone was mentioning nickel and its alloys. Why
wouldn't nickel work alone? Hysteresis too small, or something?
