    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.

    摘要： The present invention relates to an optical recording disc comprising two disc bases each having a recording layer formed on one surface side of a substrate bonded to each other by the medium of an adhesive layer with both recording layers facing each other. The adhesive layer, containing an adhesive and a reaction initiator, is hardened through polymerization reaction by the reaction initiator and photopolymerization reaction by ultraviolet-ray irradiation. For this reason, the adhesive layers of both disc bases can be bonded together entirely and uniformly and besides, the adhesive layer can rapidly get hardened, which is advantageous for enhancing productivity of a double-face type optical recording disc.

    摘要： There is provided a substrate for an optical recording disk capable of preventing non-uniformity of thickness of the transfer layer due to a camber of the substrate, and having a transfer layer excellent in uniformity of the thickness thereof. The substrate for the optical recording disk is manufactured in such a manner that a portion ranging from a center portion to an outer circumferencial portion of the substrate is forcively deformed in advance prior to the formation of the transfer layer so as to provide substantially a conical-convex shape, and thereafter, the transfer layer is formed onto a surface side of the conical-convex shape of the substrate.

    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 information recording medium has an excellent jitter characteristic with a considerable difference in reflectance between prior to and subsequent to recording. The information recording medium includes a recording layer which contains a material having a reflectance which varies by irradiation of a light beam, on which information is recorded as reflectance variations, and a substrate for supporting the recording layer, the recording layer including a metal nitride as a major component. In a method of manufacturing the information recording medium having a recording layer which includes a material having a reflectance which varies by irradiation of a light beam, on which information is recorded as reflectance variations, and the substrate for supporting the recording layer, the recording layer including a metal nitride as a major component, the method includes a recording layer forming step for forming the recording layer by a reactive sputtering method which uses a target comprised of a metal constituting a metal nitride, wherein a flow ratio Ar:N2 in an atmosphere including Ar and N2 in the recording layer forming step is set within the range of 80:10 to 10:80.
