摘要： A magnetic metallic thin film type of recording medium has particles of predetermined size uniformly distributed over a surface of a base layer, with a magnetic metallic thin film formed over these. A diamond-state carbon protective film, a carbon protective layer, e.g. of graphite, and a layer of lubricative material are successively formed over the metallic thin film, to provide lubrication and protection. As a result of surface contour modification resulting from the protrusions formed by the particles on the base layer, the contact area between the head and the recording medium is reduced, and this together with the multiple protective layers provides greatly increased durability by comparison with prior art configurations.

摘要： With the use of a novel method in which after a magnetic recording medium carrying a ferromagnetic metal thin film is heated, a protective layer is developed on the ferromagnetic metal thin film by a known plasma CVD technique while an out gas from the magnetic recording medium being eliminated by absorption, another method in which a ferromagnetic metal thin film and a protective layer are formed in succession within a vacuum chamber, or a further method in which after a non-magnetic substrate is heated, a ferromagnetic metal thin film and a protective layer are formed in succession within a vacuum chamber while an out gas from the non-magnetic substrate and the ferromagnetic metal thin film being eliminated by absorption, the atomic ratio of the hydroxyl group to a primary component metal element contained in the ferromagnetic metal thin film can be decreased at the interface between the ferromagnetic metal thin film and the protective layer.
