Somewhere in my files I have a paper from AMPEX, done many years ago, that
reports their testing indicates magnetic tape is actually very resistant to
EMP from a nuclear explosion.  According to the report, before the signal
was so degraded that no one could recover it, there would be no one left
alive in the geographic area to recover it.

I always wondered how they did the testing.

Anyway, it's a neat little document, back from the era when they were
sending out pamphlets with drawings of pieces of tape complete with arms,
legs, faces and dire warnings on how to treat your tapes (Sony did similar
pamphlets but put the arms and legs on entire reels and showed them sweating
in the heat and holding umbrellas to keep off water)- sort of like the
"Pillsbury Tape Boy".
