Abstract
A magnetic tape de-gausser includes a pair of electromagnets which are arranged to project a magnetic field through a magnetic tape reel to magnetically erase the magnetic tape. The electromagnets are mounted to be movable so as to tightly accomodate various size tape reels between the electromagnets. Structures are provided to control the separation between the electromagnets, to prevent a tape reel from destructively contacting an electromagnet, and to control the movement of a tape reel in rotation towards and away from electromagnets.
