Abstract: A head suspension for a disk drive includes a base (5) to be attached to a carriage, a load beam (3) having a rigid part (9) and a resilient part (11) supported by the base, to apply load on a data read/write head (19) arranged at a front end of the rigid part, a flexure (7) attached to the load beam and being provided with the head, and a guide face (27) formed on an edge (9a) of the rigid part where a jig is inserted, to guide the jig without wearing away the jig. The guide face is formed by providing the edge of the rigid part with an integral thin part that is tinner than the rigid part and bending the thin part, or by partly removing the edge of the rigid part. The jig is inserted into a head suspension module, which is made by arranging the head suspension and other identical head suspensions at regular intervals, such that teeth of the jig slide on the guide faces of the head suspensions to maintain spaces between the rigid parts of the head suspensions, to install the head suspension module into the disk drive such that the heads of the head suspensions face disks in the disk drive.

Abstract: A suspension comprises a load beam fitted with a flexure, an actuator base including a base plate, a hinge member thinner than the base plate, and a pair of piezoelectric ceramic elements. The piezoelectric ceramic elements displace the distal end portion of the load beam in a sway direction when supplied with voltage. Each piezoelectric ceramic element is stored in an opening portion in the actuator base. An electrical insulating cover film is pasted on each piezoelectric ceramic element. The cover film covers the opposite side faces of each piezoelectric ceramic element. The opposite end faces of each piezoelectric ceramic element are covered with an adhesive agent that fixes the element to the actuator base.
