Abstract
A data storage device includes a base, a data storage disk, an actuator arm, a suspension, and a piezoelectric actuator. The data storage disk is attached to the base and has a read/write surface defining an x-y plane. The actuator arm is attached to the base at a first pivot point to rotate parallel to the x-y plane. The suspension is attached to the actuator arm at a second pivot point, the suspension having a first end comprising a curved edge surface, and a second end supporting a head that is configured to interact with the read/write surface. The piezoelectric actuator is disposed on the actuator arm and comprises a biasing finger configured to contact the curved edge surface to rotate the suspension parallel to the x-y plane about the second pivot point. An actuator arm assembly and a method of use are also described.
