Disk drive suspension assembly with single actuator

A suspension assembly comprising:

• a load beam having a proximal end terminating in a hinge;
• a gimbal assembly mounted to the load beam;
• a base plate connected to the hinge and including an opening that defines first and second notches that face each other;
• and
• a single actuator disposed in the opening and mounted between the first and second notches, wherein the single actuator is formed of a crystal material that expands along a first axis of the single actuator and contracts along a second axis of the single actuator orthogonal to the first axis in response to a first bias voltage, and expands along the second axis and contracts along the first axis in response to a second bias voltage that is opposite in polarity to the first bias voltage;
• wherein the single actuator is configured to:
• flex the base plate when expanding along the first axis to rotate the load beam in a first rotational direction about a center of rotation located along the load beam, and
• flex the base plate when expanding along the second axis to rotate the load beam in a second rotational direction opposite the first rotational direction about the center of rotation.
