Patent number: 7313855Abstract: A method of making a multi-piece head suspension for a rigid disk drive. The method includes providing a first layer including a mounting region with an integral boss tower attached to a stiffener by one or more positioning tabs; attaching a second layer including a spring region to an interface between the mounting region and the stiffener; attaching a flexure to the stiffener; and removing the positioning tabs. The flexure can optionally be a portion of the second layer.Type: GrantFiled: December 13, 2006Date of Patent: January 1, 2008Assignee: Hutchinson Technology, Inc.Inventors: Shane J. Van Sloun, Mark R. Christianson, Stevenson J. Marek, James R. Mahoney, Mark A. Schmidt, Brandon K. Fraser, Jeffry S. Bennin

Patent number: 7312954Abstract: A stacked suspension assembly for a data storage drive having, for example, at least two suspension members with each suspension member has a bearing hole therethrough. At least one spacer is positioned between the at least two suspension members to separate adjacent suspension members Each spacer has a bearing hole therethrough. A bearing member can be inserted within the bearing holes of the at least two suspension members and the at least one spacer. The bearing member has an actuator hole into which an actuator pivot member is insertable.Type: GrantFiled: September 4, 2001Date of Patent: December 25, 2007Assignee: Hutchinson Technology IncorporatedInventors: Craig A. Leabch, Shane J. Van Sloun, Stevenson J. Marek

Patent number: 7032294Abstract: A switchable shunt has an insulating layer separating conductive lead and spring metal layers. The shunt includes a base region formed on the spring metal layer, one or more arms formed in the conductive lead layer and at least one of the insulating and spring metal layers, one or more pad regions electrically coupled to an arm and formed in at least the conductive lead layer, and one or more gaps. Each arm extends through a gap and is resiliently biased toward a shunted state with the pad region in electrical contact with the base region. The shunt is movable to an electrically open state where the pad and base regions are electrically isolated. A method of making the shunt includes etching the shunt from laminated material and pushing the arm and pad through the gap. The shunt may be operated by applying a force to the arm.Type: GrantFiled: January 22, 2003Date of Patent: April 25, 2006Assignee: Hutchinson Technology IncorporatedInventors: Stevenson J. Marek, Craig A. Leabch, Larry C. Webb, Jr., Mark A. Miller, Anthony J. Liberko, Raymond R. Wolter, Steven R. Lagergren

Patent number: 5966269Abstract: A head suspension for supporting a read/write head of a rotary data storage device combines an actuator arm and load beam in a longitudinally compact construction. The construction includes overlapping laminae with one laminae extending over a hole provided in the other laminae, resulting in a monocoque construction of the head suspension that minimizes rotational inertia while maintaining desirable levels of shock, resonance and deflection performance of the head suspension.Type: GrantFiled: August 20, 1997Date of Patent: October 12, 1999Assignee: Hutchinson Technology, Inc.Inventors: Stevenson J.
