Abstract: Provided are a computer program product, device, system, and method for compensating for a nonlinear deformation field of a tape of a tape storage system. In one embodiment, a head beam of a tape head module of a tape drive employing active skew-based TDS compensation, is segmented into linear segments which are pivotally coupled to each other. Each linear beam segment carries a portion of the transducer array of the tape head module to form a tape head module segment. The pivot angle between a pair of pivotally coupled head module segments of the tape head may be controlled by a controllable pivot actuator to provide an independently adjustable skew angle for each module segment with respect to the direction of travel of tape. As a result, it is believed that registration between the transducers of each module segment and data tracks of the tape may be improved.
