ABSTRACT:
A high density data storage tape drive includes an actuator which carries the read/write head, is driven by a voice coil and enables translational movement of the head in a direction transverse to the direction of tape travel as the tape is scrolled by the head. This permits the head to follow a servo track and position the head with a data track without skewing the transducer gap with respect to the data track. Since the actuator moving portion has stiffness and mass, it is subject to vibration at resonant frequencies, with the first or lowest resonant frequency commonly occurring within the operating bandwidth of the device. To attenuate the vibration amplitude during resonance, a damping device is provided to enable greater use of the servo system potential for track and bit density enhancement, rather than diminishing storage density performance to accommodate a worst case condition.
