    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： A thin film metal alloy magnetic recording disk has an improved protective overcoat that creates a low level of static friction in a contact start/stop disk drive. The disk has an amorphous carbon overcoat containing a transition liquid metal interlayer (TLMI). The carbon overcoat is formed by depositing an initial amorphous carbon layer to a first thickness, then depositing an interlayer material of a low-melting point metal or metal alloy (such as In or In--Nb) while maintaining the temperature of the disk substrate above the melting point of the interlayer material, and then depositing a top additional layer of amorphous carbon. Because the initial carbon layer presents a nonwetting surface, the interlayer material "balls up" on the carbon and forms discontinuous spheres of the interlayer material. The additional top layer of carbon bonds to the initial carbon layer and to the metal or metal alloy spheres. The completed disk protective overcoat presents a continuous but textured surface of amorphous carbon for the head-disk interface in the disk drive.

    摘要： A magnetic storage medium is composed of a non-wettable substrate upon which a transient liquid metal layer is deposited and maintained as a distribution of discontinuous liquid features. An intermediate metal layer is subsequently deposited in-situ in an atmosphere comprising oxygen and at least one inert gas. A magnetic layer is then deposited on the intermediate metal layer. The surface topology and magnetic characteristics of the medium are controlled by adjusting the thickness of the TLM layer and the conditions under which the TLM layer, intermediate metal layer, and magnetic layer are deposited.

    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 %.
