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.
