Abstract
An HGA includes a head slider provided with at least one head element, a precise positioning actuator fixed to the head slider for precisely positioning the at least one head element, a flexure made of a metal plate member for supporting the actuator and a load beam fixed to and for supporting the flexure. The actuator includes a pair of movable arms each formed by a metal plate that is substantially in parallel with a side surface of the head slider. Top end sections of the pair of movable arms are capable of displacing in response to a drive signal applied to the actuator along a direction crossing planes of the metal plate. The flexure and the actuator are unitarily formed.
