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.

Abstract: A suspension for disc drive having a micro actuator mechanism comprises a base plate, a connecting plate having a hinge portion thinner than the base plate, a load beam provided with a flexure, a pair of actuator elements such as PZT, etc. The micro actuator mechanism includes a pivot portion formed between a pair of slits and support walls formed on the connecting plate. The actuator elements are provided individually on the opposite sides of the pivot portion. Each support wall is a bent portion that is formed by raising an edge portion of the connecting plate in the thickness direction of the main portion of the connecting plate.

Abstract: A suspension for disc drive has a base portion including a base plate, a load beam, a pair of hinge members, a wired flexure, etc. The wired flexure has a metal base and a wiring portion on the metal base. The hinge members are fixed overlapping the rear end portion of the load beam and the front end portion of the base plate. The wired flexure extends through a gap between the hinge members and ranges over the load beam and the base plate.
