    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.

  • Publication number: 20120224282
    Abstract: An electrical connection structure for a piezoelectric element and a head suspension with the piezoelectric element employing the electrical connection structure are provided. The electrical connection structure fixes and connects a terminal of a wiring member to an electrode of the piezoelectric element, which is arranged to face the terminal, with a conductive adhesive so that no peeling due to thermal expansion occurs between the terminal and the conductive adhesive. The electrical connection structure includes a through hole formed through the terminal and a connection part formed around the through hole on an opposite side of a piezoelectric element on the terminal. The conductive adhesive is applied and solidified so that the conductive adhesive extends between a surface of the connection part and a surface of the electrode of the piezoelectric element through the through hole.

    Abstract: A load beam part main body portion's side edges include a proximal end region inclined at a first angle and a distal end region inclined at a smaller second angle. Where “L” is a distance in a suspension longitudinal direction between a supporting part's distal end portion and a dimple, a distance “a” in the same direction from the supporting part's distal end portion until an inflection point between the proximal end region and the distal end region satisfies 0.44 L?a?0.78 L. A support plate's side edges fixed to the load beam part main body portion's lower surface is located, in the suspension width direction, inward from a virtual line connecting the proximal end region's proximal end and the distal end region's distal end and outward from the proximal end region and the distal end region, and extends, in the suspension longitudinal direction, across the inflection point.

  • Patent number: 8225485
    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.

  • Publication number: 20120127614
    Abstract: A method of testing a fitted state of a pair of piezoelectric elements fitted to form an actuator between a base member and a movable member, the piezoelectric elements in the actuator being arranged side by side in opposite polarity and being electrically connected in parallel with each other, and when a voltage is applied to the piezoelectric elements, minutely moving the movable member relative to the base member in a direction in which the piezoelectric members are arranged side by side. The method detects changes in capacitance of the piezoelectric elements with respect to changes in bias voltage applied to the piezoelectric elements, the bias voltage being changed within a predetermined range, and determines a fitted state of the piezoelectric elements according to a characteristic of the detected capacitance changes. The method correctly and easily determines whether or not the piezoelectric elements are correctly fitted to the actuator.
