Abstract
Described are hard drive devise in which piezoelectric motors are used to drive the motion of actuator arms, rather than the actuator arms being controlled by electromagnetic means such as a conventional voice coil motor. Piezo-based motors suitable for use with devices of the present disclosure may include inchworm motors, brake crawler motors, ultrasonic motors (USMs), and so forth. Such piezo motors may be used to drive rotary actuator motion or linear actuator motion. Moreover, piezo motors can be provided in a compact form factor that allows the actuator arms of a stack of actuator arms to be separately controlled, either as groups or individually.
