  • High rpm hard disk drive testing
    Patent number: 10290319
    Abstract: A method for performing a flaw scan test on a hard disk drive is disclosed. The hard disk drive includes a magnetic recording medium and spindle motor associated with a predetermined rated speed. The method includes writing a test pattern to the magnetic recording medium while operating the spindle motor at a speed greater than the predetermined rated speed. The method also includes reading the test pattern at the greater speed and detecting flaws in response to reading the test pattern.

  • Skip track flaw scan methods and systems
    Patent number: 10210899
    Abstract: A method for scanning for flaws on a magnetic recording medium is disclosed. The magnetic recording medium has a first set of nonconsecutive data tracks and a second set of nonconsecutive data tracks. The method includes writing a test pattern to only the first set of nonconsecutive data tracks of the magnetic recording medium, reading of the test pattern written to the first set of nonconsecutive data tracks, and identifying flaws within the first set of nonconsecutive data tracks and the second set of nonconsecutive data tracks based on the reading the test pattern.

  • MAGNETIC STRUCTURE FREE LAYER STABILIZATION
    Publication number: 20130321954
    Abstract: A magnetic layered structure is presently disclosed comprising a pinned layer, a first anti-ferromagnetic layer that defines a magnetic orientation of the pinned layer, a free layer, a second anti-ferromagnetic layer that biases the free layer to a magnetic orientation approximately perpendicular to the magnetic orientation of the pinned layer, and a tuning layer positioned between and in contact with the second anti-ferromagnetic layer and the free layer that tunes free layer bias to a desired level.
