摘要： A lubricant composition is provided comprising a first liquid lubricant and a second liquid lubricant, wherein the first liquid lubricant contains a cyclotriphosphazene ring attached to at least one perfluoropolyether having a single terminal hydroxyl group, and the second liquid lubricant contains a perfluoropolyether having two end groups selected from hydroxyl, tertiary amine, and combinations thereof. A magnetic recording media is also provided, comprising a substrate, a magnetic layer, an overcoat layer and a lubricant layer thereon, wherein the lubricant layer is formed from the lubricant composition. A further aspect of the invention concerns a method of making a magnetic recording media comprising forming a magnetic layer on a substrate; forming a protective overcoat layer on the magnetic layer; and forming a lubricant layer on the surface of the overcoat layer by applying the lubricant composition to the surface of the overcoat layer. The lubricant composition is useful for magnetic recording media, especially for magnetic storage hard disk drives, and provides improvements such as substantially reduced lubricant thickness variations when applied to a surface of a hard disk drive.

摘要： A method is described for improving recording performance of a perpendicular media. The method includes using a dual oxide layer as a sublayer of a magnetic recording layer of the perpendicular media. The dual oxide sublayer improves recording performance, increases resistance to corrosion and allows for a thinner exchange break layer. The dual oxide layer generally includes oxides of tantalum and one of silicon or boron.

摘要： A filament post used in plasma-enhanced chemical vapor deposition has an outer shell and an inner post. An electrical potential is applied only to the inner post to ensure that there is no impact on the plasma density and the carbon film properties. The inner post and the outer shell are electrically insulated by ceramic insulators, such that no electrical potential is applied to outer shell. The stress generated in the carbon film is directly related to the electrical potential of the surface to which the film is deposited. The carbon film deposited on the outer shell of the post is not highly stressed, which significantly reduces film delamination from the filament post surfaces.
