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 disc drive system includes a load beam and a base for attachment to an actuator arm and a suspension for supporting the slider over the rotatable disc. The microactuation system includes a piezoelectric element attached between the actuator arm and the load beam and a beam connecting a stationary portion of the load beam to a moving portion of the load beam. The piezoelectric element is deformable in response to a voltage applied thereto. The beams are sufficiently compliant to permit movement of the moving portion of the load beam with respect to the stationary portion of the load beam upon deformation of the piezoelectric element.
