摘要： [PROBLEMS] To appropriately form a DTR medium, a patterned medium, or the like in a manner less likely to cause the problems of prolonged process time and increased cost.[MEANS FOR SOLVING PROBLEMS] A perpendicular magnetic recording layer 22 has a plurality of tracks 102 which define recording regions extending in a scanning direction of a magnetic head and which are arranged in parallel in a direction intersecting with the scanning direction. The perpendicular magnetic recording layer 22 has a guard band region 104 formed on its surface and provided with a groove portion 202 which extends along the tracks 102. In a cross-section of the perpendicular magnetic recording layer 22 taken along a plane perpendicular to the scanning direction, the maximum depth D of the groove portion 202 is in the range of 0.5 to 10 nm with reference to an average height (broken line 302) of the tracks 102 between which the groove portion 202 is interposed. The average height is obtained in the vicinity of the centers of the tracks 102 in a widthwise direction. The width W of a region of the groove portion 202 having a depth equal to or greater than ½ of the maximum depth is in the range of 5 to 30% of a track pitch.

摘要： In order to provide a magnetic recording medium having excellent electromagnetic conversion characteristics, a magnetic recording medium (10) is provided with a substrate (12), and a magnetic recording layer (20) formed on the substrate (12). The magnetic recording layer (20) is provided with a granular layer (32), i.e., a magnetic layer, including magnetic grains and a nonmagnetic material surrounding the magnetic grains in a section parallel to the main surface of the substrate. The ratio of the long diameter to the short diameter of each magnetic grain contained in the granular layer (32) is calculated in the section. In the histogram of such ratio, a half width at half maximum of the histogram is 0.6 or less and the variance of grain diameters of the magnetic grains in the section is 20% or less of the average grain diameter of the magnetic grains.

摘要： A process produces a belt-shaped member to be used in an image-forming apparatus is disclosed in which a toner image held on a latent-image-bearing member is electrostatically transferred under application of a voltage via the belt-shaped transfer member. The process includes the steps of melt-extruding a material containing a thermoplastic resin, from a circular die into a cylindrical film; forming the resultant cylindrical film by stretching in such a way that the cylindrical film comes to have a thickness smaller than the die gap of the circular die; and cutting the cylindrical film thus formed, into a seamless belt having a thickness of from 40 &mgr;m to 300 &mgr;m and a modulus in tension of 600 MPa or higher. The stretched cylindrical film is formed to have a thickness not larger than ⅓ of the die gap of the circular die. A belt-shaped transfer member may be produced by the above-described process. The so-produced belt-shaped transfer member is usable as a transfer belt in an image-forming apparatus in which a toner image held on a latent-image-bearing member is electrostatically transferred under application of a voltage via the belt-shaped transfer member.
