Tape degausser

Abstract

Apparatus for degaussing previously recorded tape, in reel form, in correspondingly bulk form, either of audio or visual character. It includes a conveyor for carrying the reel through the apparatus, past a pair of degaussing units which are magnetized for the degaussing steps, the degaussing units being arranged at mutually angular positions, and both at an angle to the direction of the passage of the reel through the apparatus. Means is included for reversing the polarity of the magnetism of the units repeatedly in progressively diminishing values for effecting the degaussing operation. The apparatus includes means for varying the speed of the conveyor to vary the period in which the tape is subjected to the degaussing operation. The apparatus will accommodate tape reels of great depth, either singly or in a stack, i.e., in axial direction of the reel, of more than two inches.
