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 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.

Has anyone ever characterized VCR, reel-to-reel or microfiche for silver to ensure they're not a hazardous waste?

If you are mainly trying to destroy the info on the tapes, I recommend a magnetic bulk tape eraser.

New ones seem expensive, but there are several used ones on e-bay, etc.

Thank you for all your helpful responses to my question about hazardous high school chemicals.  One more question has arisen:  How could an organization dispose of 300-400 videocassette tapes with sensitive information?  I was asked about chemical treatment =96 or burning, and would appreciate your advice.
