ABSTRACT:
To degausse high coercivity magnetic recording media, a programmable degausser includes at least first and second stations positioned at 45 degrees with respect to an anti-static conveyor belt passing through their centers and at a 90 degree angle with respect to each other. The stations include coils wound on insulated bobbins and the degausser is programmable to selectively operate continuously, operate manually, operate in response to detected recording or operate when there is no low-current or low-temperature warning alarm.
