Abstract:
A head suspension includes a base to be attached to a carriage, a load beam having a rigid part and a resilient part that connects the rigid part to the base, the load beam applying load onto a read/write head, a flexure attached to the load beam and supporting the head, an actuator attaching part located between the base and the head, and a piezoelectric element being deformable in response to a voltage applied thereto to move the head in a sway direction relative to the base. For the head suspension, it bonds the piezoelectric element with a bonding tape to the actuator attaching part and applies an adhesive to fix the piezoelectric element to the actuator attaching part.
