Re: Tape Deterioration on NOS LP Tapes
Yes I'm pretty sure there were problems with some tapes after Quantegy bought out the Ampex manufacturing facility, but it was as much with the long play tapes (457/407) as the standard play (456/406). I believe though the binder issue was eventually sorted out. The problem can be knowing which batches were affected.
I'm not sure "desperate" would be the best description. Careful baking of SSS affected archive tapes has been routine practice for many years, is normally quite safe if done with knowledge and skill, and I suspect will continue to be, although I've read reports that some baking times have had to become extended and/or temperatures higher due probably to the longer time window for the tapes to have absorbed moisture from the air.
