Have to side with Atmosphere here. He is correct. Would agree on the minimalist method of doing most things, and most of the major labels do have climate controlled storage conditions for their session masters. That is not to say many production or duplication masters tapes still get tossed. Can't tell you how many times I have been to the loading dock of a major studio back in the day, and found pallets and pallets of tape waiting for the garbage truck to pick it up....
As for tape degradation, the SSS (sticky shed syndrome) was a major problem on Ampex 406/407, 456/457, scotch 226/227, and a few others.
After Quantegy stated they had fixed the binder problem I bought 4 new cases of 456 with the new and improved binder. They were good for the first few years, but after that they slowly degraded into sticky shed just like the earlier stuff. Ended up pulling the flanges off and tossing the balance of the remaining tape into the trash.
The earlier formulations never had this problem. Same with Scotch 206/207. Have 4 cases of 207, from the early 1980s, and it still performs like new.
Losing signal was normally not an issue.
