Abstract

A linear actuator for carrying read/write heads into engagement with a recording medium includes a carriage and a subcarriage. Flexible springs mount the subcarriage to the carriage. A voice coil motor has a coil mounted on the subcarriage. Initial energization of the coil causes linear movement of the carriage flexing the springs to produce small incremental movement of the heads. Further energization of the coil causes movement of the subcarriage on the bushings to provide coarse adjustment of the actuator.
