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： This invention relates to a stamper for optical disc and a method for manufacturing an optical disc by using this stamper. A photoresist is applied to a substrate (2) and this photoresist is exposed, developed and then transferred to form a disc master which has a recess/protrusion pattern formed on its one side. The one side of the disc master (20) is etched to narrow the width of a protruding part constituting the recess/protrusion pattern, and the recess/protrusion pattern of the disc master (20) with the reduced width of the protruding part is transferred to form a stamper (30). The recess/protrusion pattern provided on the stamper (30) is transferred to form a predetermined pattern on a substrate of an optical disc.

摘要： An optical disc having pits shorter in length than 0.40 .mu.m, with the ratio of the width of the shortest pit to that of the longest pit being not less than 0.8, is formed by forming a master disc by light exposure using a light source having a wavelength not shorter than 350 nm. By taking advantage of the fact that the pit width A looking from the reflective film 20 of the optical disc is deceased to be smaller on forming the reflective film 20 than the pit width B looking from the disc substrate 10 by a value equal to the film thickness, a row of pits, generally broader than the pit width optimum when looking from the side oft the disc substrate 10, is formed on light exposure on the master disc using the laser light having a wavelength not smaller than 350 nm. The reflective film 20 is formed on the row of pits transcribed from the master disc to the disc substrate 10 to provide a pit width which minimizes the inter-pit interference or jitter of the playback RF signals. The signals are read out from the side of the reflective film 20, that is from the side of the light-transmitting layer 30, instead of from the light-transmitting layer 30.

摘要： The S/N ratio is improved for recording data to grooves (2-1,2-2) of an optical disc so that as much information as possible can be recorded at the lowest possible frequency band. An optical disc using wobble patterns to record different information has a first groove (2-1) having a first wobble pattern (22) in which one wobble period has a sharp rising edge and a gradual falling edge; and a second groove (2-2) having a second wobble pattern (24) in which one wobble period has a gradual rising edge and a sharp falling edge. Each of the first and the second wobble pattern is represented by a first fundamental and a second harmonic of a Fourier series. The polarity of the second harmonic, which is an even harmonic, of the second wobble pattern is opposite that of the first wobble pattern. A method for manufacturing this optical disc is also provided.
