摘要： Disclosed is an optical recording medium, including three or more information recording layers, characterized in that the refractive indices of a plurality of intermediate layers each disposed between an adjacent pair of the information recording layers are larger than that of a cover layer disposed between an incident surface and the information recording layer that is the closest to the incident surface. With this, crosstalk caused by light beams reflected from multiple surfaces is reduced and thereby the signal quality is improved in the optical recording medium including the three or more information recording layers.

摘要： A recording apparatus for recording sub data to an optical-disk recording medium (100) is disclosed. The optical disk recording medium (100) includes a substrate (101) having main data recorded in the form of a combination of pits and lands on one side thereof and at least a reflective layer (102) and cover layer (103) stacked on the substrate by irradiating writing-power laser light (111) to portions corresponding to predetermined-length lands formed on the optical-disk recording medium to form marks on the reflective layer correspondingly to the predetermined-length lands. The recording apparatus comprises a recording means (OP) for recording the sub data to the optical-disk recording medium so that each of the marks is formed to such a size and depth by irradiating the writing-power laser light that the level of a reading signal will be raised at the portions where the marks are formed but will be lowered at the mark-formed portions in an optical-disk recording medium produced by physically transcribing the substrate shape of the above optical-disk recording medium. A playing apparatus for playing an optical-disk recording medium (100) is also disclosed. The optical-disk recording medium includes a substrate (101) having main data recorded in the form of a combination of pits and lands on one side thereof and at least a reflective layer(102) and cover layer (103) stacked on the substrate and to which sub data is recorded in the form of marks so formed on the reflective layer by irradiating writing-power laser light (111) to the reflective layer that the level of a reading signal will be raised at portions where the marks are formed by irradiating writing-power laser light but will be lowered at the mark-formed portions in an optical-disk recording medium produced by physically transcribing the substrate shape of the above optical-disk recording medium. The apparatus comprises a reading signal generating means for generating the reading signal by detecting a return part, from the optical-disk recording medium, of reading-power laser light having been irradiated to the optical-disk recording medium; a sub data detecting means for detecting the level of the sub data on the basis of the result of sampling the reading signal generated by the reading signal generating means at a predetermined sampling point; and a judging means for judging, based on a result of determining whether the value of the sub data detected by the sub data detecting means has a correct polarity, whether the optical-disk recording medium is a authenticated disk.

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.
