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.

摘要： A display device separates a size-reduced image into a plurality of sub-areas in such a manner that a sub-area farther away from the light sources becomes wider than a sub-area closer to the light sources; compares, in each of the sub-areas, the luminance values of each pixel in a direction perpendicular to the array direction; and selects a pixel having the greatest luminance value, thereby creating line information. The display device then compares a light distribution that is a synthesis of light radiation patterns of the light sources with a luminance distribution indicated by each line information and then adjusts the emission intensity of each of the light sources.
