It seems to me that the "imprinting" phenomenon which slowly destroys
magnetic tape recordings could be eliminated by winding two tapes onto
a spool headed for storage: one tape holding the data and a second tape
with something to diffuse the magnetic field such as nickel metallization.
Or maybe a fairly thick tape, say 1 mil, would be enough to separate the
tape layers and prevent imprinting.  Or maybe just winding a blank tape
onto the same spool would be enough.  Has any of these ideas been tried?
