Over the course of a large digitizing project of mostly 1/4” tapes, we have run across a few tapes that will actually delaminate when we attempt to play them, in some cases even after the usual low level heat treatment that renders “sticky” tapes playable for transfer. We have a lot of recordings on Ampex 406, 407 and 456, and 3M 226 that I expect we’ll need to treat in order to be able to play them, but I’m wondering if anyone out there has experience with saving tapes that are actually peeling apart.
Any help would be most welcome. Thanks.
