We do not recommend it. Audio Engineering Society. Storage of polyester-based magnetic tape. Tips on saving your damaged tape. Describes the problems, the likely causes, and a proposed solution to the sticky-shed problem with magnetic tape.
Master tapes come to sticky end.
Reports problem of deteriorating sound recording tape, result of which is that the tapes are very difficult to run and may, in serious cases, jam in the recorder. The cause is thought to be the deterioration of the polyurethane binder used to hold the magnetic material onto the tape base, probably caused by hydrolysis of the polyurethane brought about by atmospheric moisture adsorbed onto the tape surface. A method for temporarily reducing the problem so that copy recordings can be made is described. A Guide for libraries and archives. Focuses on how to properly store and care for magnetic media to maximize their life expectancies.
