ABSTRACT:
A Head Arm Assembly includes a head slider having at least one head element, an arm member for supporting the head slider at one end section, an actuator, mounted to the other end section of the arm member for rotationally moving the arm member in a direction substantially parallel with a recording medium surface around a horizontal rotation axis of the arm member, a load generation unit for generating a load for energizing the head slider in a direction toward the recording medium surface by rotationally moving the arm member in a direction substantially orthogonal to the recording medium surface around a vertical rotation axis, and a limiter unit for restraining the arm member from rotationally moving more than a predetermined limit around the vertical rotation axis in a direction away from the recording medium surface.
