  • Assignee:
    SEAGATE TECHNOLOGY LLC - Scotts Valley CA
  • International Classification:
    G11B 5/66
    B05D 5/12
  • US Classification:
    428827, 427131
  • Abstract:
    Aspects are directed to recording media with enhanced magnetic properties for improved writability. Examples can be included or related to methods, systems and components that allow for improved writability while reducing defects so as to obtain uniform magnetic properties such as uniformly high anisotropy and narrow switching field distribution. Some examples include a recording medium with an exchange tuning layer inserted between the hard layer and the soft, semi-soft or thin semi-hard layer so as to maximize the writability improvement of the media. Preferably, the exchange tuning layer is granular and reduces or optimizes the vertical coupling between the hard layer and the soft, semi-soft or semi-hard layer of a magnetic recording or storing device.

  • International Classification:
    C23C 1434
  • US Classification:
    2041922
  • Abstract:
    A Co--Pt based magnetic alloy which has been sputtered with an oxide or nitride of a primary constituent of the magnetic layer, e. g. , CoO below about 10 at. %, provides improved coercivity, squareness, and reduced noise as compared to magnetic alloys with oxygen introduced by other methods. The alloy is vacuum deposited, for example, by sputtering, and the oxide or nitride may be introduced from the sputtering target from which the magnetic layer materials come or from a separate sputtering target. Examples of such oxides and nitrides include CoO, Co. sub. 2 O. sub. 3, Co. sub. 3 O. sub. 4, CrO. sub. 2, Cr. sub. 2 O. sub. 3, TiO. sub. 2, Ta. sub. 2 O. sub. 5, Al. sub. 2 O. sub. 3, WO, CoN, Co. sub. 2 N, TiN, TaN, CrN, NiN, etc.
