Optical recording medium

Abstract

[Object] To provide an optical recording layer that is capable of controlling a reflectance and a transmittance of each recording layer and obtaining good recording properties in each recording layer [Solving Means] An optical recording medium 10 includes a substrate 11 and two or more layers of recording layers 121, 122, and 123 that contain Pd, O, and M (M is one or more elements of Zn, Al, In, and Sn), O is contained in an amount greater than a stoichiometric composition thereof when M is completely oxidized (into ZnO, Al2O3, In2O3, and SnO2), and in a case where a recording layer is an nth recording layer of the two or more layers of recording layers 121, 122, and 123 as counted from an opposite side of an incident side of recording light, a Pd content therein is less than that in an n−1th recording layer.
