I should have also mentioned that when bulk erasing
media, you really want to start with the media as
close to the magnetic field as possible, and slowly
move it away (preferably rotating as you do), then
turn off the field. You want to randomize the magnetic
particles (which an AC field does well), not align
them (which a collapsing field does pretty well.)
