Abstract
The present invention provides an optical recording medium realizing reduced manufacturing cost of the optical recording medium. An optical recording medium 10 includes: a substrate 1; a recording layer 2 formed on the substrate 1, containing In, Sn, Pd, and oxygen, and containing oxygen atoms more than stoichiometric composition of the case where the In and the Sn are completely oxidized; and a light transmission layer 3 formed on the recording layer 2.
Claims5
An optical recording medium comprising:
- a substrate;
- a recording layer formed on the substrate, containing In, Sn, Pd, and oxygen, and containing oxygen atoms more than stoichiometric composition of the case where the In and the Sn are completely oxidized;
- and
- a light transmission layer formed on the recording layer.
A method of manufacturing an optical recording medium in which a recording layer is formed on a substrate and an optical transmission layer is formed on the recording layer, comprising the step of forming the recording layer containing In, Sn, Pd, and oxygen on the substrate by sputtering while passing oxygen gas using an In2O3 target, an SnO2 target, and a Pd target.
