摘要： A suspension is provided with a load beam and a flexure including a tongue on which a slider is mounted. A limiter is formed by cutting and raising a part of the tongue. The limiter includes a bent portion and arm. The tongue has an opening that is left after the limiter is cut and raised. The opening and limiter are formed along a center line of the tongue. A distal end of the dimple is in contact with a back surface of the slider through the opening.

摘要： A head suspension has a base, a piezoelectric element, a load beam, and a wiring member to supply electric power to the piezoelectric element so that the piezoelectric element deforms to move the load beam relative to the base. The wiring member has a conductive base layer, an insulating layer, and a wiring layer layered in this order. The wiring layer has a wiring electrode. The piezoelectric element has an element electrode. A through hole is formed through the conductive base layer and insulating layer, to expose the wiring electrode to the element electrode. A projection is formed on at least one of the wiring electrode and element electrode, to face the other electrode through the through hole. The projection brings the electrodes into contact with each other and a conductive adhesive joins the electrodes and together.

摘要： A flexure with conductors is provided with a flexure tail portion. The flexure tail portion includes a metal base, an electrically insulating layer, and a conductive member. The metal base is formed with a plurality of apertures. A damper is attached to the flexure tail portion. The damper includes a viscoelastic member and a metallic constrained plate. The viscoelastic member has first and second surfaces. The first surface of the viscoelastic member is secured to the flexure tail portion. The constrained plate is secured to the second surface of the viscoelastic member. The constrained plate extends longitudinally relative to the metal base along the conductive member. The conductive member and the constrained plate face each other with the viscoelastic member therebetween.

摘要： A head suspension 31 has a piezoelectric element 13 that deforms in response to a voltage applied thereto, a base plate 33 having an attaching part to which the piezoelectric element 13 is attached, and a load beam 35 having a flexure 39. A front end of the load beam 35 moves in a sway direction according to the deformation of the piezoelectric element 13. The head suspension 31 includes adhesives that attach the piezoelectric element 13 to the attaching part. The adhesives are applied to and hardened at the attaching part one by one. At least one of the adhesives that is first applied to and hardened at the attaching part is electrically insulative.The head suspension 31 properly maintains electric insulation between the piezoelectric element 13 and the attaching part, sufficiently demonstrates original functions, and secures a rigidity balance and proper vibration characteristic.

摘要： A head suspension for a disk drive includes a plate that is easily and correctly be attached to a carriage of the disk drive and improves the attaching accuracy and strength of the head suspension to the carriage. The head suspension includes the plate and a load beam. The plate has a boss that is formed separately from the plate. The boss has a base fixed to the plate and a protrusion fitted into a hole of a carriage arm of the carriage. The plate has a through hole. The base of the boss is fitted into the through hole and is fixed to the plate. Under this state, the protrusion of the boss protrudes from a first face of the plate, and the base of the boss protrudes from a second face of the plate. An end face of the base of the boss serves as a contact face for jig.
