Abstract
The density of winding of tape onto a reel at high winding speeds is improved by oscillatory longitudinal translation of a portion of the tape, to induce tape tension oscillations. This substantially precludes slipping of the layers on the reel. To initiate the tension oscillations, a tape tension controller in a video tape recorder is vibrated by a motor whose torque is varied periodically. In another embodiment, the spindle of a guide roller is mounted for eccentric rotation by a drive motor.
