Richard, I don't follow your meaning re. "...the metal work where it was
kept."

Vinyl could well be the best archive for sound
recordings. My master tapes are mainly deteriorated
now, sadly, even though I was lucky enough never to
have used that Ampex type where the oxide eventually
fell off the acetate. Only the DAT tapes still play as
well as new, and they probably won't play at all one
day. This is another "digital" the DATs probably will
either play or not, the analogue tapes just steadily
deteriorate :-)
I have not had the much publicised CD deterioration
problems with any of my pre recorded discs that I
still play. Not sure about my "own burns" yet long
term but so far so good!

All of the major tape brands, Ampex, Scotch, Agfa, BASF, had binder
problems at various times. We knew about the serious problems because the tape
would shed oxide when run through the recorder but its likely some binder
problems did not show up for years. Some old tape can be salvaged by baking at
a low temperature but not all. I think storage methods have a lot to do with
tape longevity. Its interesting to me that no one at the time was concerned
with the life of the media itself. We assumed that if stored under reasonable
conditions it would last forever.
The longest lasting recordings seem to be the metal work where it was
kept.
