    摘要： The object of the present invention is to enable the identification of double-layer disc type (recordable double-layer disc, rewritable double-layer disc and ROM-type double-layer disc) to be easily and accurately performed. The method for identifying double-layer disc contains obtaining a reflectance of each light by irradiating light of different wavelengths under focused state to each layer of a double-layer disc loaded in an optical apparatus, and identifying if the double-layer disc is a recordable double-layer disc, a rewritable double-layer disc or a ROM-type double-layer disc corresponding to the combination of reflectance of each obtained light. It is preferable that the wavelength of one light is a wavelength for DVD-based disc and the wavelength of the other light is a wavelength for CD-based disc.

    摘要： The present invention is aimed at providing a dual-layer phase-change optical recording medium which allows a high-density recording and a recording, where the optical recording medium has a high recording sensitivity even to a low power light with a short wavelength such as blue laser beam, does not cause noises such as jitter, has superior overwrite performance and favorable archivability, allows easier focusing and tracking and enables a compatibility with a ROM. Therefore, it provides an optical recording medium including a substrate and, on the substrate at least a first recording composite layer, an intermediate layer, a second recording composite layer and a cover substrate in this order, wherein the groove depth of the cover substrate is such that the magnitude of a push-pull signal of the first recording composite layer is equal or greater with respect to a push-pull signal of the second recording composite layer.
