A mechanism is provided to position a transducing head (40) with respect to a selected radial track (34) of a rotatable recording disc (30) in a disc drive including an actuator arm (16) and a suspension load beam (18) connected to the actuator arm (16). A plate (42, 70) is hingedly attached to the load beam (18), and a flexure (22) is attached to the plate (42, 70). A slider (24) supporting the transducing head (40) is attached to the flexure (22). A microactuator (44, 74a, 74b, 74c, 74d) is attached to the plate (42, 70) and is operable in response to electrical control signals to move the plate (42, 70) relative to the load beam (18) in the general plane of the load beam (18) to selectively position the transducing head (40) proximate to the selected radial track (34) on the rotatable recording disc (30). |
