  • Plasma polish for magnetic recording media
    Patent number: 9159353
    Abstract: Fabrication methods for magnetic recording media that use a plasma polish are disclosed. For one exemplary method, a film of a magnetic recording medium is deposited, and a top surface of the film is polished utilizing a plasma formed by a noble gas to smoothen the top surface of the film. A subsequent layer is then deposited onto the polished top surface of the film. A top surface of the subsequent layer has a reduced roughness by being deposited on the polished top surface of the film.

  • System, method and apparatus for onset magnetic oxide layer for high performance perpendicular magnetic recording media
    Patent number: 9082442
    Abstract: Perpendicular magnetic recording media has been enhanced by controlling the initial growth of magnetic oxide layers and increased magnetic isolation between the grains in the initial magnetic layer. An onset magnetic oxide layer is sputter deposited in an argon-oxygen gas mixture between the main CoPtCr-oxide magnetic layers and the underlying Ru layer. The insertion of the onset magnetic oxide layer enhances the coercivity of the oxide magnetic layers and also improves the nucleation field. The media signal-to-noise ratio and bit error rate also are significantly improved due to the improvement of the initial segregation of Co magnetic grains in the magnetic oxide layers.
