    摘要： In a gradation display method, an image is divided into pixels having fine areas, this pixel is furthermore divided into very fine pixels (Si) having very fine areas, and then gradation is displayed based upon a ratio of a colored very fine pixel (Si) with respect to all of very fine pixels (Si) within a pixel. Also, the above-described colored very fine pixel (Si) is formed by both a first growth core which is formed by increasing the number of colored very fine pixels of a single cluster, and a second growth core which is formed by increasing the number of colored very fine pixels of another single cluster.

    摘要： Disclosed is a magnetic recording medium and a method for manufacturing the same to provide a magnetic recording medium reducing medium noise and having excellent thermal stability. The magnetic recording medium includes a substantially amorphous seed layer and a polycrystal underlayer made of crystal grains having a substantially columnar structure, the polycrystal underlayer contacting thereto. In a boundary between the seed layer and the underlayer, fine grooves having a period up to as large as the magnetic layer crystal grain diameter are formed in the disc circumferential direction. Accordingly, the magnetic recording medium is allowed to have a grain shape with a value obtained by dividing the average grain diameter for the disc circumferential direction by the average grain diameter for the disc radial direction of no less than 0.5 and no more than 0.9, thus achieving simultaneously reduction of the medium noise and thermal stability.

    摘要： Since the surface roughness of a recording layer get larger in the process of fabricating a patterned medium, the spacing between a head and the medium is widened. As a result, the recording performance and corrosion resistance of the medium are degraded. In the patterned medium, a recording layer includes one layer of a crystalline magnetic film or plural layers of crystalline magnetic films, and a magnetic film of an amorphous structure located on the outermost surface of the crystalline magnetic films. The compositional elements of the magnetic film of the amorphous structure are identical to those of the crystalline magnetic film located immediately under the magnetic film. In a fabrication method thereof, the surface of the crystalline magnetic film is turned into amorphous in order to form the magnetic film of the amorphous structure.
