摘要： By use of a substrate which can be stably formed and has a relatively small groove depth, a very high density optical recording medium having good recording/reading characteristics is provided. In an optical recording medium 20 of a surface incidence type, in which a reflective layer 23, a recording layer 22 containing a dye as a main component and a cover layer 24 are sequentially formed on a substrate 21 having guide grooves formed therein, a guide groove part on a far side from a plane of incidence of a recording/reading light beam 27 on the cover layer 24 is set as a recording groove part, and reflected light intensity in a recorded pit portion formed in the recording groove part is increased by a phase shift and is set higher than reflected light intensity in unrecorded.

摘要： The optical storage medium comprises a substrate layer and a data layer disposed on the substrate layer, the data layer having a mark/space data structure being arranged in tracks, wherein on a first track, the marks are enlarged in length and the spaces are shortened in length, and on an adjacent track, the marks are shortened in length and the spaces are enlarged in length. The track pitch between adjacent tracks is particularly below a diffraction limit of lambda/2*NA of a pickup for reading of the data.

摘要： The present technology relates to an optical recording medium for realizing an optical recording medium capable of high-capacity recording. A groove and a land are formed, the groove being concave and the land being convex when seen from a side of a laser light incident surface, both of the groove and the land being recording tracks where recording or reproduction of information is performed. According to this recording layer, a pitch between the groove and the land that are adjacent recording tracks is within a range of 250 nm to 200 nm. Moreover, recording or reproduction of information is performed with respect to the recording tracks by irradiation of laser light whose wavelength is 400 nm to 415 nm by an optical system whose NA is 0.85+0.1.

摘要： To provide a recording method and a storage medium for BCA data with high reliability for a storage medium and a method for reproducing BCA data from the storage medium, and an information recording apparatus and an information reproducing apparatus. In a conventional optical disk, low reliability data is recorded in a data area of BCA. Thus, the thickness of a film material for use in a recording layer oriented to BCA data or close to the inner periphery of the storage medium in the vicinity thereof is formed in uniform thickness by using a substrate of the storage medium, the substrate being formed by being suctioned by means of adsorbing mechanisms (56, 71, 72) formed in an arc shape so as to integrated two of the adsorbing mechanisms to be adjacent to each other. Therefore, the information recorded in a BCA (burst cutting area) or recorded close to the inner periphery of the storage medium in the vicinity thereof can be recorded precisely and stably.
