Not magnetic tapes - the adhesive that holds the particles to the
substrate deteriorates in 15 years or so. I know this from bitter
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.....
