Abstract
A microactuation system selectively alters a position of a transducing head carried by a slider in a disc drive system with respect to a track of a rotatable disk having a plurality of concentric tracks. The microactuation system includes a head suspension having a first portion and a second portion coupled by one or more flexible hinges. An electroactive element is attached to the first portion of the head suspension at one end and the second portion of the load beam at the other end. The electroactive element bends in response to a control signal applied thereto. The hinge is sufficiently compliant to permit movement of the first portion with respect to the second portion of the head suspension.
