ABSTRACT:
Method and apparatus are provided for counteracting tape interlayer slip in a magnetic tape drive (20) which has a swingarm (84) in a tape path between a tape supply reel and a tape take-up reel. So long as an interlayer slip is not detected, a reel motor (30) for the tape supply reel is driven in accordance with a primary strategy related to a position of the swingarm (84). Upon detection of the interlayer slip, the reel motor (30) is driven in accordance with a secondary strategy. In a first embodiment, the secondary strategy depends on the velocity of the reel motor; in a second embodiment, the secondary strategy depends on the velocity of the reel motor and the swingarm average position.
