Abstract
An actuator is coupled between a head and flexure and gimbal elements, the actuator providing submicron positioning of the head while reducing undesirable vibrations of the flexure and gimbal elements. Such an actuator may have a frame that surrounds a cavity, the frame having an opening disposed adjacent to the head and a wall disposed on an opposite side of the frame from the opening. One or more active elements are disposed in the cavity and attached to the frame, the active element separated from the wall and having a dimension that varies in size in response to a control signal, with a moveable element coupled to the active element and to the head.
