摘要： A disc drive suspension has a base portion including a baseplate and a plate member, a load beam, a pair of hinge members, and a flexure with conductors. The flexure passes through a gap between the hinge members and ranges over the load beam and the base portion. A thin-walled portion is formed by partial etching on that region of a front end portion of the plate member of the base portion which faces the flexure. A thin-walled portion is also formed by partial etching on that region of a rear end portion of the load beam which faces the flexure.

摘要： 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.

摘要： A microactuator mounting section is disposed between a base section and a load beam. A microactuator element formed of a piezoelectric element is contained in an element accommodation portion in a plate portion. The plate portion has a stationary part secured to the base section and a movable part secured to the load beam. The stationary part and the movable part are connected to each other by a pair of arm portions. Each arm portion comprises a first extending portion and a second extending portion. The first extending portion extends longitudinally relative to the load beam from a front end of the stationary part toward the movable part. The second extending portion extends transversely inward relative to the plate portion from the first extending portion so as to be continuous with the movable part.

摘要： A slider supporting apparatus is provided with a flexure formed of a metal plate having spring characteristics. The flexure comprises a gimbals portion including a tongue, a first support portion which supports one longitudinal end of a slider, a second support portion which supports the other end of the slider, and a spring portion composed of a pair of flat springs. Convexes and concaves of each flat spring are alternately formed along a surface direction of the flexure by etching. The flat springs extend to a length which allows the slider to be inserted between the support portions when subjected to a tensile load, and contract to a length such that the slider can be held between the support portions when subjected to no tensile load.

摘要： 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.
