    摘要： A flexure mounted on a load beam of a disk drive suspension, including a metal base formed of a stainless-steel plate; and a conductive circuit arranged along the metal base. The conductive circuit includes an insulating layer on the metal base; and a conductor on the insulating layer. The conductor includes a thin conductor portion formed in a first region (A1) which is part of the conductive circuit in a longitudinal direction; and a thick conductor portion formed in a second region (A2) which is another part of the conductive circuit in the longitudinal direction, the thick conductor portion being thicker than the thin conductor portion. The flexure includes a flexure tail portion having an opening formed in the metal base; a bent portion of the metal base which is bent in a thickness direction at the opening; and a trace curved portion curved in the thickness direction at a position facing the opening. The trace curved portion includes the thick conductor portion.

    摘要： A suspension includes a load beam and a flexure. The flexure has a metal base and a conductive circuit portion. The conductive circuit portion has an insulating layer formed on the metal base, and a conductor formed on the insulating layer. The conductive circuit portion includes a first region which constitutes a part of the conductive circuit portion in the longitudinal direction, and a second region which constitutes another part of the same in the longitudinal direction. The conductor includes a thin conductor portion having a first thickness arranged in the first region, and a thick conductor portion having a second thickness arranged in the second region. The second thickness is greater than the first thickness.

    摘要： An interleave circuit includes a metal base, an insulating layer, a first conductor member having first branch conductors, a second conductor member having second branch conductors, and a jumper conductor, which is a part of the metal base. The jumper conductor includes a branch-side metal portion, a pad-side metal portion, and a bridge portion. The bridge portion is formed between the branch-side metal portion and the pad-side metal portion. The branch-side metal portion electrically conducts to connecting terminals of the first branch conductors via branch-side connecting members. The pad-side metal portion electrically conducts to an electrode pad via a pad-side connecting member. The bridge portion includes a crossover portion which crosses over a third conductor member.

    摘要： A cutting jig cuts bonding material of a terminal joint between a magnetic head's slider and a flexure's wiring terminal. A base of the jig receives the slider. A blade moves along the base and faces a front side wall of the slider in a moving direction. An upright portion of the jig is formed on the base and has a stop face that faces a rear side wall of the slider in the moving direction. The blade moves toward the slider to come into contact with the bonding material, and is pressed to the front side wall of the slider. The bonding material is interposed in the moving direction while the rear side wall of the slider is brought into contact with and is stopped by the stop face when the slider is set on the base and the bonding material is cut.

    摘要： In a first terminal portion, a first conductor, a terminal element as a first protection, and a first gold-plating layer are provided. The first terminal element is thicker than a base nickel layer of a slider terminal portion. The first gold-plating layer is provided with a first roughening processed portion. An electrically conductive paste contacts the roughening processed portion. In a second terminal portion, a second conductor, a terminal element as a second protection, and a second gold-plating layer are provided. The second terminal element is thicker than the base nickel layer. The second gold-plating layer is provided with a second roughening processed portion. An electrically conductive paste contacts the second roughening processed portion.

    摘要： A method of surely removing a read/write slider from a flexure without large displacement of the slider, the slider attached to the flexure of the head suspension through an adhesive, comprises heating the slider so that the adhesive is heated through an adhered surface of the slider being in contact with the adhesive; and applying ultrasonic vibration to the slider so that the adhered surface of the slider vibrates at ultrasonic frequency with respect to the adhesive.
