摘要:
A microactuation system is disclosed for selectively altering 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 having a base for attachment to an actuator arm and a head suspension for supporting the slider over the rotatable disc. A microactuation system includes a piezoelectric element attached between the base and the head suspension of the load beam and beams or hinges connecting the head suspension to the base. The piezoelectric element is deformable in response to a voltage applied thereto. The beams are sufficiently compliant to permit movement of the head suspension with respect to the base upon deformation of the piezoelectric elements.
