Abstract:
A method for counteracting longitudinal oscillations in a magnetic tape as it passes over a head in a tape drive system includes the steps of passing the magnetic tape over the head, detecting the occurrence of longitudinal oscillations in the magnetic tape, and generating counteractive longitudinal oscillations in the magnetic tape that are substantially 180° out of phase with the longitudinal oscillations to substantially cancel the longitudinal oscillations.
