Patent number: 9019646Abstract: An apparatus includes a write element configured to apply a magnetic field to write data on a portion of a heat-assisted magnetic recording media in response to an energizing current. An energy source is configured to heat the portion of the media being magnetized by the write element. A preheat energizing current is applied to the write element during an interval before writing the data to the portion of the media. The preheat energizing current does not cause data to be written to the media and brings at least one of the write element and driver circuitry into thermal equilibrium prior to writing the data on the portion.Type: GrantFiled: March 14, 2013Date of Patent: April 28, 2015Assignee: Seagate Technology LLCInventors: Tim Rausch, Jon D. Trantham, John West Dykes, Housan Dakroub, Charles Paul Henry, Edward Charles Gage, Raul Horacio Andruet, James Gary Wessel, James Dillon Kiely, Bruce Douglas Buch, Barmeshwar Vikramaditya

Publication number: 20150085632Abstract: A heat generating component of a slider is energized at a predetermined frequency. The heat generating component changes a spacing between a medium and the slider. A temperature response proximate a media-facing surface of the slider is measured while the heating element is energized. Based on the measured temperature response, a determination is made as to whether the media-facing surface is contaminated. In response to determining that the media-facing surface is contaminated, remedial action is taken.Type: ApplicationFiled: September 25, 2013Publication date: March 26, 2015Applicant: Seagate Technology LLCInventors: James Dillon Kiely, Jon D.
