Abstract
A microactuator is employed in a disc drive system to finely position a transducing head adjacent to a selected track of a rotatable disc. The disc drive includes an actuator arm, a load beam attached to the actuator arm, and a flexure supporting a slider carrying the transducing head adjacent to a surface of the rotatable disc. The microactuator is formed integrally with the load beam, and is attached to the flexure so that displacement effected by the microactuator deflects a portion of the load beam to finely position the flexure and the head-carrying slider with respect to the selected track of the rotatable disc.
