Matthew M Johnston: Method and apparatus for fly height testing using light emitting diodes. Seagate Technolgy, Theodore M Magee, Westman Champlin & Kelly PA, September 23, 2003: US06624892 (4 worldwide citation)

A method and fly-height tester include a moving medium and a slider mount that holds a slider in proximity with the medium so that the slider flies relative to the medium. At least one light emitting diode generates a light that is directed by optics so that it reflects off the medium and the slider ...

Xing Song, Qixu Chen, Charles Leu, Rajiv Y Ranjan: High coercivity magnetic recording medium comprising a thin CoCrTa intermediate layer. Seagate Technolgy, McDermott Will & Emery, November 21, 2000: US06150016 (3 worldwide citation)

A high areal density magnetic recording medium exhibiting high remanent coercivity and high coercivity squareness is formed with a thin CoCrTa intermediate layer to provide appropriate crystalline orientation and surface morphology for nucleation and growth of a magnetic layer thereon. The present i ...

James Dillon Kiely, Jon D Trantham: Detection and remediation of head contamination. SEAGATE TECHNOLGY, Hollingsworth Davis, October 24, 2017: US09799358

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 m ...
