HEAD SUSPENSION HAVING ACTUATOR IN WHICH PIEZOELECTRIC ELEMENT IS BONDED WITH BONDING TAPE, ACTUATOR AND METHOD OF ATTACHING PIEZOLECTRIC ELEMENT WITH BONDING TAPE

摘要

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.

1. A method of attaching a piezoelectric element to a head suspension that includes a base to be attached to a carriage and turned around a spindle of the carriage, a load beam having a rigid part and a resilient part, the resilient part connecting the rigid part to the base, the load beam applying load onto a head at a front end distal to the base to write and read information, a flexure attached to the load beam and supporting the head to connect the head to read/write wiring, an actuator attaching part located between the base and the head, to enable the head to be moved in a sway direction relative to the base, and a piezoelectric element fixed to the actuator attaching part, the piezoelectric element being deformable in response to a voltage applied thereto to move the head in the sway direction relative to the base, the method comprising:
bonding the piezoelectric element with a bonding tape to the actuator attaching part; and applying an adhesive to fix the piezoelectric element to the actuator attaching part after the bonding step.
