<p>A disc drive (10) having an actuator arm (16) to support a slider (24) carrying a transducing head (56) adjacent a selected data track (34) of a disc (30) having a plurality of concentric data tracks (34) includes a microactuator (54) on a leading edge surface (60) of the slider (24) to effect fine positioning of the transducing head (56) with respect to the selected track (34). The microactuator (54) includes a spatial region (63, 65) on the leading edge surface (60) of the slider (24). A microactuator element (72, 74, 92, 94, 142, 172) spans the spatial region (63, 65) and is responsive to a voltage to selectively expand and contract, thereby bending to alter the position of the slider (24) and the transducing head (56).</p> |
