Patent number: 8395863Abstract: A contact pad includes a first layer of material with a first yield strength and a second layer of material with a second yield strength is laminated to the first layer. A third yield strength of the laminated composite of the first layer and the second layer exceeds the first yield strength and the second yield strength due to the Hall-Petch phenomenon. An overcoat covers an edge of the first layer and the second layer of the contact pad to prevent wear. A method of creating the contact pad or other microelectronic structure includes depositing a first layer of material with a first yield strength on a substrate. A second layer of material with a second yield strength is deposited on the first layer. An edge of the first layer and the second layer is coated with an overcoat material to prevent wear of the first and second layers.Type: GrantFiled: July 29, 2010Date of Patent: March 12, 2013Assignee: Seagate Technology LLCInventors: Jeremy A. Thurn, Ibro Tabakovic, Maissarath Nassirou, Brian Karr, Kurt W. Wierman, Joachim W. Ahner

Patent number: 7593189Abstract: A head gimbal assembly (HGA) is provided. The HGA includes a suspension that has a suspension coefficient of thermal expansion (CTE) and a slider that has a slider CTE. A bonding element attaches the slider to the suspension. A compensation layer, having a compensation CTE, is located on the suspension. The compensation layer serves to compensate for a thermal distortion of the slider. A method of forming a HGA is also provided. The method includes providing a suspension having a suspension CTE and forming a slider having a slider CTE. The method further includes attaching the slider to the suspension and depositing a compensation layer, having a compensation CTE, on the suspension. The compensation layer serves to compensate for a thermal distortion of the slider.Type: GrantFiled: June 30, 2006Date of Patent: September 22, 2009Assignee: Seagate Technology LLCInventor: Jeremy A.

Patent number: 7277257Abstract: A transducer-level microactuator selectively positions a transducer portion of a slider radially with respect to circumferential data tracks of a rotatable disc. The slider includes a slider body having a leading edge and a trailing edge, a transducer body and a flexure body. The transducer body is spaced from the trailing edge of the sliding body and includes at least one transducer element. The flexure body extends from the trailing edge of the slider body and includes a first anchor point connected to the slider body and a second anchor point connected to the transducer body. The basecoat layer is deposited on the trailing edge of the slider body and substantially surrounds the flexure body wherein a gap separates the flexure body from the basecoat. A first actuation assembly is formed on the basecoat and a second actuation assembly is formed on the transducer body adjacent the slider body.Type: GrantFiled: December 5, 2003Date of Patent: October 2, 2007Assignee: Seagate Technology LLCInventors: Roger L. Hipwell, Jr., Kyle M. Bartholomew, Lance E. Stover, Wayne A. Bonin, Jeremy A. Thurn, Zine-Eddine Boutaghou

Publication number: 20060061910Abstract: A sensor comprises a transducer portion including a semi-permanently deformable portion. A deformation of the semi-permanently deformable portion in response to an activation energy deforms the transducer portion. The deformation is retained after the activation energy is removed. In another embodiment of the invention, a transducer comprises a body having an active element, a magnetostrictive element and a magnet having a magnetic field. The magnetic field causes a deformation of the magnetostrictive portion thereby adjusting the position of the active element.Type: ApplicationFiled: November 2, 2005Publication date: March 23, 2006Applicant: Seagate Technology LLCInventors: Jeremy Thurn, Declan Macken, Dale Egbert

Publication number: 20050088784Abstract: A slider includes a slider body having a trailing edge and a leading edge. The slider also includes a thin film structure deposited in layers on the trailing edge. The thin film structure includes a write transducer configured to read and write to a storage medium. The thin film structure also includes a non-thermally activated actuator at least partially formed with the write transducer and configured to move the write transducer relative to the trailing edge.Type: ApplicationFiled: October 22, 2003Publication date: April 28, 2005Applicant: Seagate Technology LLCInventors: Declan Macken, Jeremy Thurn, Lance Stover, Ned Tabat, John Pendray
