I open up my old backup tapes & use a cutting blade to cut through the tape
spool in a couple of places, to you end up with hundreds of pieces of tape,
no more than a couple of centimetres long. Then I generally throw them in a
couple of different bins.
Tape de-gaussers usually aren't much good - they were mostly made for erasing
open reel tape that used ferric oxide particles.
Backup tapes normally use metal particle tapes that need a much stronger
magnetic field to effectively erase them.
