When I worked on this gear, we kept a magnet assy from a CDC 9762 80mb 
drive under the bench in a safe place, and used it to bulk-erase any 
tapes as needed. The magnets from a RA81 failed cartridge are very small 
and powerful, will do nicely. I keep a few in my workshop for gen duty 
screw pickup, etc.
