Patent number: 8869385Abstract: An apparatus for positioning a component relative to an associated component. The apparatus includes a component receiver and onto which the component is disposed. The apparatus also includes an associated component receiver and onto which the associated component is disposed. The component receiver orients the component into a position for retaining the component to the associated component. The apparatus further includes a retention device driver for inserting a retention device, the retention device retaining the component to the associated component in the position. The apparatus also includes an optical position verifier for verifying the position of the component and the associated component.Type: GrantFiled: September 24, 2007Date of Patent: October 28, 2014Assignee: HGST Netherlands B.V.Inventors: Jen-Yuan Chang, Khaled M. Fawzi, Russell D. Moates, Edgar D. Rothenberg

Patent number: 8675311Abstract: An interleaved conductor structure for electrically connecting the read/write electronics to a read/write head in a hard disk drive is provided. The interleaved conductor structure may allow for an increased characteristic-impedance range, greater interference shielding and a reduction of signal loss that is contributed by a lossy conductive substrate. The electrical traces may have different widths, be offset, or even wrap around each other at the via connections.Type: GrantFiled: December 22, 2010Date of Patent: March 18, 2014Assignee: HGST Netherlands B.V.Inventors: John T. Contreras, Nobumasa Nishiyama, Edgar D. Rothenberg, Rehan A. Zakai, Yiduo Zhang

Patent number: 8270120Abstract: A flex cable assembly for a head stack assembly of a hard disk drive comprises a flex cable for conducting data signals from the head stack assembly to a connector. The flex cable comprises a dynamic loop section between a termination for the head stack assembly and the connector. A constrained layer damper is attached adjacently to an area of the flex cable that is configured to receive the coupler. The constrained layer damper extends into the dynamic loop section of the flex cable.Type: GrantFiled: November 30, 2007Date of Patent: September 18, 2012Assignee: Hitachi Global Storage Technologies, Netherlands B.V.Inventors: Jeffrey Kerner, Kirk B. Price, Robert C. Reinhart, Edgar D. Rothenberg, Jr-Yi Shen

Patent number: 8144431Abstract: A hard disk drive flex cable assembly conveys data between a connector to a host system and a head stack assembly. It comprises a flex cable which in part has a first end for coupling to the connector, and a second end for coupling to the head stack assembly; and a stiffener coupled to the second end. The stiffener comprises an end formed to approximate a J-shape. A filling material is applied to the concave surface of the J-shape, whereby a dynamic response frequency of the flex cable assembly is moved away from a dynamic response frequency of the head stack assembly upon which the flex cable assembly is coupled.Type: GrantFiled: April 4, 2007Date of Patent: March 27, 2012Assignee: Hitachi Global Storage Technologies, Netherlands B.V.Inventors: Jen-Yuan Chang, Robert C. Reinhart, Edgar D. Rothenberg, See C. Young

Patent number: 7881016Abstract: A latching mechanism for a flex cable bracket. The latching mechanism includes a position limiter. The position limiter prevents movement of an actuator assembly installed thereon. The latching mechanism also includes a spring clip. The spring clip has spring functionality and a cantilever beam to retain the actuator assembly when installed thereon. The latching mechanism further includes an orientation position limiter. The orientation position limiter prevents a rocking motion of the actuator assembly. The position limiter and the spring clip and the orientation position limiter are integrated into structure of the flex cable bracket.Type: GrantFiled: January 31, 2007Date of Patent: February 1, 2011Assignee: Hitachi Global Storage Technologies, Netherlands, B.V.Inventors: Jen-Yuan Chang, Ta-Chang Fu, Edgar D.
