    摘要： A system and method for improving the durability and reliability of recording media used in hard drives is disclosed. A protective overcoat made by depositing a diamond like carbon (DLC) layer over a magnetic layer and then depleting a portion of the DLC protective layer of hydrogen before it is coated with a Perfluoropolyethers (PFPE) using an in-situ vapor lubrication technique. The portion of the DLC layer which is depleted can be data zone of the media so that the lubricant-bonding ratio is higher for the landing zone than it is for the data zone.

    摘要： Ion beam-deposited, nitrogen-doped C:H films having substantially lower resistivities than undoped ion beam-deposited C:H films and suitable for use as hard, abrasion-resistant overcoat layers for magnetic recording media, such as hard disks, are formed by supplying a mixture of hydrocarbon and nitrogen gases to an ion beam generator. Nitrogen atom content of the films is controlled to within from about 5 to about 25 at. % by appropriate selection of the ratio of hydrocarbon gas flow to nitrogen gas flow. The resultant IBD i-C:HN films exhibit a reduced tendency for charge build-up thereon during hard disk operation by virtue of their lower resistivity vis-à-vis conventional a-C:H materials.
