Abstract: A method for assembling a head-gimbal assembly of a hard disk drive, the method including the steps of dispensing adhesive onto a top surface of a gimbal tongue, wherein the gimbal tongue is positioned adjacent to a load beam with a dimple extending from its top surface, and wherein the gimbal tongue is configured with at least one support feature that inhibits its deformation toward the dimple when subjected to downward pressure with respect to the dimple; positioning a slider on which a magnetic head is mounted adjacent to the top surface of the gimbal tongue; and pressing the slider onto the adhesive and toward the dimple of the load beam.

Abstract: A method of manufacturing a head suspension includes a punching process, a positioning process, and an affixing process. An objective part on the head suspension to which a damper 73 is affixed includes a discontinuous section 72. The punching process punches a damper material into the damper 73 whose shape corresponds to the shape of the objective part excluding the discontinuous section 72. The positioning process positions the damper 73 to the objective part so that the damper 73 avoids and surrounds the discontinuous section 72, and the affixing process affixes the damper 73 to the objective part. The method secures a uniform damping effect among manufactured head suspensions and improves the yield of dampers and head suspensions without deteriorating the functions and performances of the head suspensions.

Abstract: A base material has a vibration damper provided detachably on a liner through an attaching surface. An apparatus is used when punching the vibration damper piece from the base material. The punched vibration damper piece is attached on an objective portion of a semi-finished head suspension. The apparatus includes a hollow punch and a punch drive mechanism. The hollow punch has a tooth portion at a distal end and a hollow internal surface that has a holding force larger than an attaching force of the vibration damper to the liner. The hollow punch punches the vibration damper piece out from the base material to hold the vibration damper piece on the hollow internal surface. The punch drive mechanism drives the hollow punch backward and forward in a punching direction, so that the vibration damper piece is punched with the tooth portion without punching out the liner.
