摘要： A load/unload-type head suspension is capable of suppressing frictional coefficient variations. The head suspension has a head and a tab that is slid and guided along a ramp block in a read/write apparatus, to move the head away from a hard disk to a retract position. The tab is provided with microscopic irregularities to suppress frictional coefficient variations when the tab is guided along the ramp block. A center line average roughness (Ra) of the microscopic irregularities being greater than 0.2 μm or smaller than 0.6 μm.

摘要： The head suspension includes a base plate turned around a spindle, a load beam, and a flexure. The load beam includes the rigid part, a resilient part, and a head. A base end of the rigid part is attached to the resilient part, which is supported with the base plate. The head is for writing and reading data to and from a disk and is positioned at a front end of the rigid part to receive load from the load beam. The flexure is attached to the load beam and supports the head. A rail is formed along each side edge of the rigid part by bending the side edge in a thickness direction of the rigid part. The rail is continuous from the front end to the base end of the rigid part. The base end of the rigid part widens to form a wide part. The rail has a longitudinal curve around the start of the wide part. The longitudinal curve is provided with a deformable part that is more easily deformable in the longitudinal and vertical directions of the rail than the remaining parts.

摘要： 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.

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.
