发明名称 Perpendicular magnetic recording medium and method of manufacturing the same
摘要 Embodiments of the present invention improve the production efficiency of a perpendicular recording medium while ensuring the scratch resistance thereof. In order to realize high production stability in the high speed production of perpendicular recording media, a target is not provided with a texture of a low melting point or the ratio thereof is decreased. Thus according to one embodiment of the present invention, upon forming a layer having an element of a low melting point in the constituent layers of a perpendicular recording medium, a target can be made using an alloy powder previously formed of an intermetallic compound having a melting point higher than 660° C., thereby preventing thermal deformation.
