摘要： A novel optical disc which, while having interchangeability with a conventional MD or MD data, has a capacity far exceeding the capacity of these optical discs, and an optical disc device. The optical disc and the optical disc device take into account the constraints of the skew accompanying the increased recording density. By setting the jitter produced when recording random pattern signals on one track only to not more than 8.4% and by setting jitter increase on recording signals also on both side neighboring tracks to not more than 4.9%, the skew margin in the radial direction of not less than ±0.7° and that in the running direction (circumferential direction) of not less than ±0.6° are assured.

摘要： A large capacity recording medium is formed by bonding at least two disc-shaped recording plates to provide a structure adapted to absorb any manufacturing errors in the direction of the height of the recording medium. The second substrate (3) has a projecting section (23) entering a plate receiving recess (11) of the first substrate (2) keeping a gap (C1) between the front of it and the plate receiving recess (11). A raised section (6) of the first substrate (2) may be exposed through an exposure in a cartridge.

摘要： There is provided a method of manufacturing an optical recording medium. This method comprises the steps of forming a photoresist layer (21) on a substrate (20); exposing a predetermined area (R) of the photoresist layer (21) formed on the substrate (20) to form a plurality of trains of depressions in the photoresist layer (21); removing the photoresist layer (21) between the adjoining depression trains to form a master (50); plating the master (50) with a metal (51); separating the metal (51) coating to form a master stamper (52); replicating the master stamper (52) repeatedly an odd number of times to form a mother stamper (55); replicating the mother stamper (55) to form a resin substrate; and forming at least a light-transparent layer on a surface of the resin substrate on which the mother stamper (55) is replicated. The method can mold a pattern of microscopic depressions and projections with a high accuracy.
