ABSTRACT:
An optical recording medium including an opto-magnetic recording medium is provided with a protective layer of an oxide-nitride mixture on either one side or both sides of the optical recording layer. Because of the provision of the mixture layer, the optical recording layer not only has an improved durability such as a corrosion resistance but also can have improved writing and reading efficiencies through adjustment of the refractive index of the mixture layer.
