摘要： When wire-bonding process is effected, a head assembly is held between a pair of clamp members. A head slider is urged against a microactuator. The urging force is transmitted to the microactuator through second adhesive layers. Since the second adhesive layers are positioned symmetrically around the rotational axis of the head slider, the urging force tends to act along the rotational axis. The microactuator is simultaneously urged against the support member. The urging force is transmitted from a first adhesive layer to the support member. Since the first adhesive layer extends around the rotational axis, the urging force tends to act along the rotational axis. The head slider is thus allowed to keep a uniform attitude. The microactuator is also allowed to keep a uniform attitude. The microactuator is prevented from suffering from substantial bending stresses.

摘要： A head assembly includes a suspension having a gimbal, a flexible printed wiring sheet having a plurality of conductor patterns and adhered to the suspension, first and second piezoelectric actuators mounted on the gimbal, and a head slider mounted on the first and second piezoelectric actuators. The first and second piezoelectric actuators are adhered to the gimbal at end portion adhesion portions symmetrical with respect to the center of pivotal motion thereof and are adhered to the head slider at end portion adhesion portions on the opposite side disposed symmetrically with respect to the center of pivotal motion similarly. Consequently, when a voltage is applied to the first and second piezoelectric actuators through the flexible printed wiring sheet, a couple of forces can be generated which vary the posture of the head slider only in one direction around the center of pivotal motion.
