US Patent:
6704163, Mar 9, 2004
Filed:
Sep 10, 2001
Appl. No.:
09/950267
Inventors:
Michael E. Detjens - Altoona WI
Craig A. Leabch - Saint Cloud MN
Assignee:
Hutchinson Technology Incorporated - Hutchinson MN
International Classification:
G11B 548
US Classification:
3602445
Abstract:
An actuator assembly for supporting a read/write device in an information storage device having an actuator arm having at least one tower protruding from a first surface of the actuator arm, a loadbeam having at least one tower receiving means for receiving the at least one tower, wherein the at least one tower is shaped to extend into the at least one tower receiving means when the loadbeam is joined with the actuator arm, and wherein the tower and tower receiving means are configured such that deforming the at least one tower when within the at least one tower receiving means provides a deformation interference between the at least one tower and the at least one tower receiving means that reduces movement of the tower receiving means relative to the tower.

Method Of Operating Switchable Shunts For Integrated Lead Suspensions

US Patent:
6723931, Apr 20, 2004
Filed:
Jan 22, 2003
Appl. No.:
10/349048
Inventors:
Stevenson J. Marek - Hutchinson MN
Craig A. Leabch - Saint Cloud MN
Mark A. Miller - Hutchinson MN
Anthony J. Liberko - Hutchinson MN
Raymond R. Wolter - Hutchinson MN
Steven R. Lagergren - Litchfield MN
Assignee:
Hutchinson Technology Inc. - Hutchinson MN
International Classification:
G11B 540
US Classification:
200 16D, 200283
Abstract:
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.

US Patent:
6965499, Nov 15, 2005
Filed:
Apr 23, 2003
Appl. No.:
10/421180
Inventors:
Yiduo Zhang - Plymouth MN, US
Raymond R. Wolter - Hutchinson MN, US
Craig A. Leabch - Saint Cloud MN, US
Assignee:
Hutchinson Technology Incorporated - Hutchinson MN
International Classification:
G11B005/48
US Classification:
3602348, 3602458
Abstract:
A head suspension or head suspension component article configured for solder ball bonding of a head slider to electrical traces on article. The article including electrical traces formed from electrically conductive material with the electrical traces having a bonding region adapted for electrical bonding to a head slider. Also included is a support structure providing support for at least portions of the electrical traces and including a head slider mounting region adapted to receive the head slider. This structure is configured to mechanically and thermally isolate the bonding region of the electrical traces from the head slider mounting region to reduce mechanical and thermal effects of a solder ball bonding process on the article during solder ball bonding of the head slider to the electrical traces. The support structure may be reduced at or around the bonding region, or the conductive material may be increased to dissipate more heat.

Filed:
Nov 5, 2002
Appl. No.:
10/288395
Inventors:
Keith W. Carlson - Hutchinson MN, US
Dennis A. Boismier - Shorewood MN, US
Galen D. Houk - Hutchinson MN, US
Craig A. Leabch - Saint Cloud MN, US
Assignee:
Hutchinson Technology Incorporated - Hutchinson MN
International Classification:
G11B 5/48
US Classification:
3602663
Abstract:
Apparatus and method for grounding a flexure of a head suspension assembly to a moving support such as an actuator arm or an E block close to a preamplifier, write driver or other wiring such as a flexible circuit located on the moving support in a disk drive assembly, including connecting a metal substrate layer of the flexure to a ground on the moving support closely adjacent the preamplifier or flexible circuit to minimize ground loop interference with signals on the traces. The invention includes a variety of arrangements to secure the metal substrate layer to the moving support.

Filed:
Oct 18, 2004
Appl. No.:
10/967514
Inventors:
Craig A. Leabch - Saint Cloud MN, US
Assignee:
Hutchinson Technology Incorporated - Hutchinson MN
International Classification:
G11B 5/596
US Classification:
3602448
Abstract:
A head suspension for supporting a read/write head in a dynamic rigid disk data storage device and applying a load force on the read/write head in a load direction when the storage device is in operation, the suspension comprising an elongated loadbeam portion extending along a longitudinal axis having a bending spring rate in the load direction. The loadbeam comprises a rigid mounting portion at a proximal end of the loadbeam portion for attaching the loadbeam portion to an actuating mechanism, a rigid load portion at a distal end of the loadbeam portion for supporting an assembly configured to carry the read/write head, and a spring portion integrally formed with the mounting region and load region and having partially etched regions with a thickness that is smaller than the mounting region and load region. The spring portion appreciably affects the bending spring rate.
