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.

An optical recording medium including a substrate and two or more recording layers that contain Pd, O, and M (M comprises at least one of Zn, Al, In, and Sn), where O is contained in an amount greater than a stoichiometric composition thereof when M is completely oxidized (into ZnO, Al2O3, In2O3, and SnO2). An nth recording layer of the two or more recording layers, as counted from an opposite side of an incident side of recording light, has a Pd content that is less than that of an (n−1)th recording layer.
