Abstract: A suspension comprises a load beam, a base plate, and a hinge member. The hinge member has an end portion lapped and fixed on the proximal portion of the load beam, a base plate mounting portion lapped and fixed on the base plate, and flexible portions situated between the end portion and the base plate mounting portion. The flexible portions are situated individually on the opposite sides of an opening formed in the hinge member, and are elastically deformable in its thickness direction. An end portion of the base plate and the hinge member are fixed on each other by means of laser welds in positions near the flexible portions. The laser welds are formed individually in regions that extend in the axial direction of the hinge member from the flexible portions.

Abstract: A suspension for disc drive 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. A covering material such as an adhesive agent that fills the space between the peripheral edge portion of the piezoelectric ceramic element and the actuator base forms a cover portion that covers the opposite end faces and the opposite side faces of the ceramic element.

Abstract: A suspension for disc drive 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. Each piezoelectric ceramic element is stored in an opening portion in the actuator base and fixed to the actuator base by means of an adhesive layer. The adhesive layer includes an electrical insulating adhesive agent and a large number of fillers of an insulating material mixed in the adhesive agent. The fillers are interposed between each piezoelectric ceramic element and the actuator base to secure a clearance for electrical insulation between the two.
