Patent number: 8390957Abstract: A head suspension 11 includes a load beam 17 having a base plate 13, a hinge part 15 resiliently supported by the base plate, and a rigid part 14 joined with the hinge part, a reinforcing plate 25 joined with the rigid part at a portion proximal to the hinge part, and a bend 17c on the load beam formed by bending the load beam toward the reinforcing plate along an edge 25a of the reinforcing plate. Only by accurately joining the reinforcing plate with the load beam in a sway direction (a widthwise direction of the head suspension), the load beam is easily and properly bent without torsion to form the bend 17c along the edge of the reinforcing plate that defines a bending strength boundary.Type: GrantFiled: July 15, 2010Date of Patent: March 5, 2013Assignee: NHK Spring Co., Ltd.Inventors: Kenichi Takikawa, Hideki Fuchino, Masaki Yokota

Patent number: 8094415Abstract: A suspension is provided with a base plate, load beam, and flexure. The base plate includes a boss portion, a first region situated on a side closer to a slider with respect to a center of the boss portion, and a second region situated on a side more remote from the slider. A pair of first projections are formed in the first region. A pair of second projections are formed in the second region. The projections project in the thickness direction of the base plate. The boss portion is inserted into a hole in an actuator arm, and the projections contact a suspension support portion of the actuator arm. The boss portion is pressurized from inside to be enlarged, whereby the base plate is fixed to the inner peripheral surface of the hole of the actuator arm.Type: GrantFiled: April 7, 2009Date of Patent: January 10, 2012Assignee: NHK Spring Co., Ltd.Inventors: Masaki Yokota, Akira Nojima
