摘要:
Disclosed is an optical recording medium comprising a transparent substrate, a transferred layer of preformat pattern formed on one side of the transparent substrate, and a recording layer laminated on the preformat patterns formed on the surface of the transferred layer, wherein the transferred layer is composed of a three-layer structure with a first layer composed of a first organic compound layer composed of a first organic compound simple substance, a mixed layer composed of a mixture of the first and a second organic compound, and a second organic compound layer composed of a second organic compound simple substance, layered in the above order from the transparent substrate and a method for manufacturing the optical recording medium.
