    摘要: An object of the present invention is to provide a phase-change optical recording medium of an amorphous recording mark type. The optical recording medium is a write once type medium capable of decreasing the degradation of an information signal which has been already recorded. The recording layer of the optical recording medium according to the present invention includes a first recording layer and a second recording layer. The first recording layer comprises a first composition which can be changed into another composition more stable in an amorphous state by combining with a component included in the second recording layer.

    摘要: A double-layer optical disk having characteristics that are less wavelength dependent, allows the use of a pickup comprising a light beam of a different wavelength to read each layer accurately and stably. In the double layer optical disk which comprises, a first reflection layer carrying first information, a spacer layer, and a second reflection layer carrying second information, each laminated on a transparent substrate having a specific refractive index thereby allowing a pickup to read said first and second information, the first reflection layer is formed by laminating a metal layer made of a metal thin film and a dielectric layer made of a dielectric having a refractive index higher than the refractive index of the transparent substrate.

    摘要: An apparatus for manufacturing a substrate of an optical recording disk having a transfer layer of uniform thickness. The apparatus forcibly deforms a portion of the substrate ranging from the center portion to an outer circumferential portion so as to provide a substantially conical-convex shape prior to the formation of the transfer layer. The apparatus forms the transfer layer onto a surface side of the conical-convex shape of the substrate.
