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 comprises a baseplate having a boss portion, a beam portion with a flexure, and a hinge member. The hinge member includes a connecting portion that can bend in the thickness direction thereof between the baseplate and the beam portion. If the length of the suspension from a pivot portion on the distal end portion of the beam portion to the center of the boss portion is 14.5 mm, the thickness of the baseplate is 0.175 mm or greater, the width of the baseplate is 4.5 mm or greater, the length of the connecting portion of the hinge member is 0.7 mm or shorter, and the length of the baseplate is 5.04 mm or shorter.

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.
