Abstract

A data storage device includes a stack of data storage disks, a head stack assembly, and a piezoelectric motor. The head stack assembly includes an arm, a load beam, a head and a tail. The arm is configured for pivotal motion about a longitudinal axis of an actuator shaft. The load beam is attached to the arm. The head is attached to the load beam and is configured to interact with a surface of one of the disks, the surface defining an x-y plane. The tail is disposed on an opposite side of the actuator shaft from the arm and has a first engagement surface that is parallel to the x-y plane. The piezoelectric motor includes a piezoelectric element and a contact tip. The piezoelectric element comprises a first mounting surface. The contact tip is disposed at the first mounting surface and frictionally contacts the engagement surface.
