    摘要： 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.

    摘要： Perpendicular magnetic recording (PMR) media and methods of fabricating PMR media are described. The PMR media includes, among other layers, a perpendicular magnetic recording layer and a cap layer that are exchange coupled. The magnetic recording layer and the cap layer may be exchange coupled through direct contact, or may be exchange coupled over a coupling layer. In either embodiment, the cap layer is formed from a CoPtCr alloy having a concentration of Cr in the range of about 15-22 at %.

    摘要： Perpendicular recording media with sublayers of dual oxide dopant magnetic materials are disclosed. The magnetic layer may comprise multiple sublayers of magnetic materials. In each sublayer, dual oxide dopants are incorporated. The compositions of the sublayers can be the same or different depending on the application. The magnetic layer may be deposited using a target comprising a mixture of CoPtCrB and dual oxides as dopants. The layer deposited with such targets can be the entire magnetic layer or a sublayer.
