摘要： PROBLEM TO BE SOLVED: To decide whether the defect generated on the surface of a substrate is the defect that arises from the defect existing on a prescribed pattern or not, in the substrate which is manufactured so that a repeated pattern is transferred on the major surface.
SOLUTION: A plurality of substrates in which a prescribed pattern is transferred are manufactured using an injection molding device for transferring a stamper on which the prescribed pattern is formed, by performing the step of manufacturing the disk substrates one after another. After the formation of magnetic films on the plural disk substrate, the defects existing on the surfaces of the disks 1, 2, and 3 are detected, and the fixed defects 4 existing at approximately the same positions each other are extracted by the detection result of the defects existing on the major surfaces of the three disks 1, 2, and 3, respectively. The fixed defects 4 are separated from random defects 1b, 2b, and 3b, on each of the major surfaces of the disks 1, 2, and 3, by extracting the fixed defects 4 from each of the disks 1, 2, and 3.

摘要： PROBLEM TO BE SOLVED: To measure the eccentricity easily and accurately in a short time by measuring the eccentricity based on the coordinates at the centers of the information recording region, and the inner and outer circumferential fringes of an information recording disc. SOLUTION: A magnetic disc 1 is mounted on a rotary disc 112 and turned at a predetermined period. A pickup drive section 122 shifts an optical pickup 121 to an arbitrary position of a data track DT and delivers a tracking signal for 1 turn while a spindle motor 111 detects the GP transmitting position of the rotary disc 112 and generates a GP signal. Based on a radial displacement signal detected 132a from these signals, a signal analyzing section 132a determines the radial displacement of the track DT (difference between the center of rotation A and the center of the track). Similarly, the differences determined between the centers N, G (center of outside diameter) of the inner and outer fringes of the disc 1) and the center of rotation A. Finally, the distance between the center of track T and the center of inside diameter N is measured as the eccentricity of the disc 1 at the time of conversion into a spatial coordinate having the center of outside diameter G as the center of coordinate.
