    摘要: The present invention provides a magnetic disk in a discrete track medium and a patterned medium, which prevents the loss of the magnetically recorded data when a head of a magnetic disk device contacts the magnetic disk, and a manufacturing method thereof. A magnetic disk has a protrusion as a non-magnetic member formed on a disk surface to prevent a head from being in contact with a recording section. When the protrusion formed in a disk substrate collides against the head, the protrusion 7 does not collapse, and accordingly, the recording layer is not damaged. Alternatively, concave and convex portions are formed on the substrate surface to use the convex portion as the protrusion.

    摘要: A patterned magnetic medium includes: a substrate; a soft magnetic underlying film, a nonmagnetic film, an intermediate film and a recording layer which are formed on a principal surface of the substrate; a first protective film formed in contact with the recording film; a second protective film formed in contact with the first protective film; and a third protective film formed in contact with the second protective film. Moreover, the recording layer has a pattern structure formed by making a magnetic film come into contact with a concavo-convex pattern of a nonmagnetic material. The first protective film and the third protective film include carbon as the main constituent element and the second protective film is a wet-coated polymer film. High adhesion between carbon and the wet-coated polymer film can prevent peeling off and the wet-coated polymer film as a cushioning material absorbs impact.

    摘要: Manufacturing processes for phase change memory have suffered from the problem of chalcogenide material being susceptible to delamination, since this material exhibits low adhesion to high melting point metals and silicon oxide films. Furthermore, chalcogenide material has low thermal stability and hence tends to sublime during the manufacturing process of phase change memory. According to the present invention, conductive or insulative adhesive layers are formed over and under the chalcogenide material layer to enhance its delamination strength. Further, a protective film made up of a nitride film is formed on the sidewalls of the chalcogenide material layer to prevent sublimation of the chalcogenide material layer.
