摘要： A hard coating for a cutting tool being highly resistant to both wear and seizure; and a cutting tool coated with the hard coating. This hard coating is a multilayer film including two or more of the following layered in alternation: first coating layers including AgaCu1-a; and second coating layers including a nitride, oxide, carbide, carbonitride, or boride containing at least one element selected from among group IVA, VA, and VIA elements, aluminum, and silicon. Since the atomic proportion for the first coating layers is between 0.2 and 0.4, inclusive, the layering pitch of the first and second coating layers is between 0.2 and 100 nm, inclusive, and the total thickness is between 0.2 and 10.0 μm, inclusive, the coefficient of friction and cutting resistance can be reduced by the inclusion of silver in the coating, and provide a hard coating that exhibits superb lubricity and resistance to seizure.

摘要： According to one embodiment, a method of manufacturing a magnetic recording medium comprises forming a protective film on a ferromagnetic recording layer containing Cobalt (Co) on a substrate and forming a recess in both the protective film and the ferromagnetic recording layer at a part where a nonmagnetic layer is to be formed. The method further comprises removing Co from a part of the recess of the ferromagnetic recording layer to form the nonmagnetic layer that separates magnetic patterns made of the ferromagnetic recording layer containing Co. The nonmagnetic layer has an identical chemical composition as the ferromagnetic recording layer, except for the nonmagnetic layer having a lower Co concentration than the magnetic patterns.
