Sorry, should be more specific. I meant prints.

Not magnetic tapes - the adhesive that holds the particles to the

experience. It also matters greatly if the tapes are stored head
or tail out. The print-through resulting from long-term storage
head out can obliterate material on neighboring layers. Cassettes
- well they don't last long at all.
There have been library archive studies that have put a similar
short life on CD's, and even less on DVDs - the laminate deteriorates.
Obviously again, storage conditions make all the difference, just
with like photographs.

Properly stored negatives, the olde analog film stuff, can be
printed after how many years? I have some that are 30 years old and
are still printable.....
