Anecdote: A long time ago, I had an industrial strength bulk tape eraser. The thing drew about 10 amps. When you put a tape on it and turned it on, the tape vibrated and made a noise rougly equivalent to a steam jackhammer. One had to take the tape at least 10 feet away from the eraser before switching it off to avoid magnetizing the tape from the half cycle when the switch opened. At this time, I had some low density TRS-80 disks I wanted to erase, and I figured this would be a good way to do it. I rubbed each disk on the deguasser for about 30 seconds. As far as I could tell, not a single bit was erased. The oxide they use on disks is HARD. If you want to erase disks, make sure your deguasser is designed for the job.
