We had, past tense, a bulk eraser at the tv station that was apparently 
made for erasing the 10.5" and 14" NAB reels of audio tape.  But it fell 
into disuse when the 3/4" u-matic format for video came along as it was not 
strong enough to wipe all the way to the center.

Somewhere in my collection I have one of the hand held ones that the Shack 
sold for cassette tapes, and it worked well on floppies, including 3.5".

For audio work, it is very important that the media be removed very slowly 
from the field these generate before the power switch is released.  Turn it 
off while the tape is still in contact, and you likely will leave the tape 
very hissy & noisy, with a distinct, it will peg the vu meters thump once 
per turn of the reel.
