Abstract: In order to prevent a molded disc substrate (2) from generating a separation pattern, a molding die (1) includes a stationary die (6) and a movable die (7), and an outer circumference ring (16) for molding an outer circumference end of the disc substrate (2). The outer circumference ring (16) is so mounted as to be movable along forward and backward directions in parallel with a moving direction of the movable die (7) toward the stationary die (6), and has a retaining surface (39) for retaining the outer circumference of the molded disc substrate (2).

Abstract: A magneto-optic disk (10) has recording tracks (11) formed along concentric grooves (12) or a spiral groove (12), non-grooved portions formed in positions of the recording tracks (11), pit patterns representing information on the recording tracks (11) and formed on the non-grooved portion, and track-counting grooves (14) adapted for optically detecting that the light spot of a reading laser beam traverses a recording track (11) and provided in the non-grooved portions. Therefore, a high-speed access to a desired recording track is adequately performed while enabling high-density recording.

Abstract: A disk substrate comprises a data zone for recording and/or reproducing data and an eccentricity measurement zone (14) in which groove regions provided with spiral grooves and planar mirror regions are spatially alternated. The widths of the groove regions and those of the mirror regions formed in the eccentricity measurement zone and the distances between the grooves in the groove regions are selected so that a conventional mechanical property measuring apparatus can track a plurality of grooves formed in the groove regions as if they were a single groove.

Abstract: Optical information recording medium comprises both the land and groove faces formed as the recording tracks on the substrate. A laser beam is radiated from the rear side of the substrate for recording and reproducing, the inclination angle of the groove face comes within the range of 25 o>to 40 o>, and the arithmetic averaged roughness (Ra) of both land face and the groove face are 0.2 to 0.7 nm, respectively. An independent claim is made for method of manufacturing original disk.
