I open up my old backup tapes & use a cutting blade to cut through the tape= =20 spool in a couple of places, to you end up with hundreds of pieces of tape,= =20 no more than a couple of centimetres long. Then I generally throw them in a= =20 couple of different bins. Tape de-gaussers usually aren't much good - they were mostly made for erasi= ng=20 open reel tape that used ferric oxide particles. Backup tapes normally use metal particle tapes that need a much stronger=20 magnetic field to effectively erase them.
