Patent number: 9135938Abstract: A method of detecting a contact between a transducing head and a storage medium is provided. The method applies an input signal, having a select power level and known frequency, to an actuator for actuating the head. An output signal is obtained in response to the input signal. At least one signal component is extracted from the output signal at the same or a harmonic of the same known frequency as the input signal applied to the actuator. Whether the at least one extracted signal component indicates a contact between the head and the medium is determined. The power level of the applied wave pattern is increased incrementally until the extracted signal component indicates a contact between the head and the storage medium.Type: GrantFiled: May 20, 2014Date of Patent: September 15, 2015Assignee: SEAGATE TECHNOLOGY LLCInventors: Dongming Liu, Lin Zhou, Adam Karl Himes, Lee Clifford Knippenberg, Michael Thomas Johnson

Patent number: 6744602Abstract: Herein is disclosed a method and apparatus for reducing particle collection on a slider or gimbal tongue. The gimbal tongue is shaped so as to interact with airflow within a disc drive to direct particles away from the slider and gimbal tongue. The leading edge of the gimbal tongue overhangs the leading edge of the slider. As air current approaches such a geometry, a large pocket of slow moving, high pressure air is created just upwind of the slider. Thus, as particulate matter encounters this pocket, the matter is slowed and its momentum is partially dissipated. A vent is provided in the gimbal tongue. The vent permits an escape route for the particles to move to an area of lower pressure, located on the other side of the gimbal tongue.Type: GrantFiled: February 8, 2002Date of Patent: June 1, 2004Assignee: Seagate Technology LLCInventors: Ram Mohan Rao, Scott Edward Ryun, Zine Eddine Boutaghou, Adam Karl Himes

Patent number: 6714384Abstract: A printed circuit head interconnect of a head gimbal assembly (HGA) has different material thicknesses in different regions of the printed circuit head interconnect. The printed circuit head interconnect includes a lamination sheet of materials having dielectric materials and conductive materials. The regions which need to have a lower stiffness are made thinner than the rest of the regions. The rest of the regions are made thick and robust enough to support the HGA. A method of reducing the thicknesses of the printed circuit head interconnect includes applying a resist mask pattern having a plurality of openings with different sizes so as to obtain different thicknesses of the materials in different regions of the printed circuit head interconnect.Type: GrantFiled: December 7, 1999Date of Patent: March 30, 2004Assignee: Seagate Technology LLCInventors: Adam Karl Himes, Kevin Jon Schulz

Patent number: 6704157Abstract: Passive damping of a disc drive structural member is achieved using a tuned resonance passive damping circuit. This circuit can, for example, be connected to a head gimbal assembly that has a piezoelectric micro-actuator. The circuit can be tuned to the sway frequency of the micro-actuator. The circuit is configured to dissipate mechanical energy as heat, effectively damping the structure to which it is attached.Type: GrantFiled: April 16, 2001Date of Patent: March 9, 2004Assignee: Seagate Technology LLCInventors: Adam Karl Himes, John Wright, David Gordon Qualey, David Allen Sluzewski
