Publication number: 20060046210Abstract: A method for creating a pattern on an exposure site of a material blank using an exposure apparatus includes providing a mask having a first mask pattern. The mask is positioned between the exposure apparatus and the material blank. The exposure site of the material blank is exposed. One or more additional exposure events are performed for patterning the exposure site of the material blank. Between each exposure event, the exposure site of the material blank is repositioned in a lateral direction with respect to the mask. Between successive exposure events involving the first mask pattern, there is a relative movement between the mask and the material blank of a distance less than or equal to a length of the first mask pattern.Type: ApplicationFiled: August 26, 2004Publication date: March 2, 2006Applicant: Seagate Technology LLCInventors: Jianxin Zhu, Lance Stover

Publication number: 20050122630Abstract: A slider includes a transducer-level microactuator for selectively positioning a transducer portion of the 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 means is formed on the basecoat and a second actuation means is formed on the transducer body adjacent the slider body.Type: ApplicationFiled: December 5, 2003Publication date: June 9, 2005Applicant: Seagate Technology LLCInventors: Roger Hipwell, Kyle Bartholomew, Lance Stover, Wayne Bonin, Jeremy Thurn, Zine-Eddine Boutaghou

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

Publication number: 20050057841Abstract: A head with a heating element and control regime therefor is disclosed. In embodiments described, the control regime or controller energizes the heater or heating element to provide intermittent heating between read or write operations to optimize transducer temperature and operating characteristics or parameters of a data storage device. In particular, in one embodiment described, the controller provides a low amplitude signal or current to provide low grade thermal heating. In another embodiment, the controller provides a high amplitude signal or current to preheat the transducer portion for write operations.Type: ApplicationFiled: September 12, 2003Publication date: March 17, 2005Applicant: Seagate Technology LLCInventors: Lance Stover, Jane Gates, Ladislav Pust, John Brand
