I work at a pharmaceutical company. When we had a large quantity of VCR tapes that needed to be destroyed, the company that shreds our documents collected then shredded the tapes.

Have experience using a Varian ~10 tesla NMR to erase various magnetic media. Very quick and effective, just ensure there are no metal parts on the media which would pull it=0A into the magnet.

VCR and reel to reel use magnetic methods to store information - you're talking iron and/or chromium oxides on plastic film. Microfiche (microfilms) come in various types, one of which is the classic silver film negative, yes. But others=0A are all organic - for example, diazo compounds.

I would assume snuggling your recorded videocassettes up to an NMR magnet would take care of scrambling them. I'd love to see an empirical test by someone on the list.
Thank you for all your helpful responses to my question about hazardous high school chemicals. One more question has arisen: How could an organization=0A dispose of 300-400 videocassette tapes with sensitive information? I was asked about chemical treatment - or burning, and would appreciate your advice.
