So there you have it. I'm not asserting that all
diskettes were manufactured as well as this IBM one but I stand by
what I suggested, I would certainly try IPA again if I had to. By the 1970s I would think
a diskette surface had come a
long way from my dad's RAMAC days and even the 1/2" magnetic tape from the 50s
and 60s, where I would be considerably
more reticent trying this.
Well, they're your disks. I've seen a system for reading magnetic tape
where a continuous bath was used to combad sticky-shed, but there were
no comments on the condition of the medium after reading.
If these were my disks, I wipe them down with cyclomethicone. That
would at least lubricate them and leave them (after evaporation) in
pretty much the same state as you started.
Remember that a fatty acid usually was used as a medium lubricant when
these disks were manufactured. The last thing in the world you want to
do is dissolve this and remove it.
But, as I remarked, they're your disks. I've certainly seen my share of
8" CPT floppies--and 1960s 1/2" tape.
