I agree with Scott Phillips. I'd like to read everyone's comments about
this on the ARSC site if everyone is willing. Because I have some acetate
tapes from circa 1957 that are dried, curled, and that I want to preserve.
I'll tell something that was told to me about a possible rescue method
by Mitchell Heller, who's been an engineer involved in recording since the
early 1950s: humidity. Mitchell said the basic problem is that acetate tape
dries out, and curls as a result. He recommended putting a piece of wet
cloth or paper towel in at least one corner of a tape enclosure, the more
corners the better, trying to cover all openings of the enclosure with something
like plastic wrap to trap the moisture inside, and letting it sit for a
while. He said that would rehydrate the tape and cause it to flatten enough
to be played successfully.
Despite my problems with a few acetate tapes I've never had the energy
to try it, so I don't know whether it works. Others probably will. In any
case, that's my contribution. I hope to read others' thoughts about the topic.
It would be a shame if it wasn't on list, this is important. Perhaps
Richard Hess has some information, I believe he has played this tape type
