<p>An optical information recording medium comprising a substrate, an optical recording layer formed over the surface of the substrate, and a protective layer covering the optical recording layer. The protective layer incorporates an antireflection means, such as a laser beam absorbing means, a laser beam scattering means or a laser beam transmitting means, for preventing the reflection of a laser beam applied to the optical recording layer. An optical information recording medium comprising a substrate, an optical recording layer formed over the surface of the substrate, a protective layer covering the optical recording layer, and a buffer layer interposed between the optical recording layer, and a buffer layer interposed between the optical recording layer and the protective layer. At least either the protective layer or the buffer layer incorporates at least one of antireflection means, such as a laser beam absorbing means, a laser beam scattering means and a laser beam transmitting means, for preventing the reflection of a laser beam. The buffer layer facilitates precisely forming recording bits in the optical recording layer by locally deforming the optical recording layer by a laser beam.</p> |
