    摘要： A method of manufacturing an optical information recording medium that has a substrate having a signal recording layer formed on one principal surface thereof; and an optically transparent layer formed on the signal recording layer and made from a radiation cure type resin. According to the method, when the optically transparent layer is formed, the radiation cure type resin is supplied onto the substrate, and the radiation cure type resin is applied over the substrate by spinning the substrate at a predetermined number of application revolutions in a spin coating method. The number of revolutions of the substrate is increased after the application of the resin, and radiation is irradiated to cure the radiation cure type resin while the number of revolutions of the substrate is increased.

    摘要： A method of manufacturing an optical information recording medium to/from which signals can optically be recorded and reproduced. The recording medium includes a signal substrate (100), a signal recording layer (110), and a transparent cover layer (125) having a first transparent layer (115) and a second transparent layer (120), which is harder than the first transparent layer (115). Signals can be recorded and reproduced to and from the recording medium by a light transmitted to the signal recording layer through the transparent cover layer (125). The first transparent layer is formed so as to have a first predetermined distribution of thickness. The second transparent layer is formed so as to have a second predetermined distribution of thickness to make the total thickness of the transparent cover layer (125) uniform. The first transparent layer (115) may be made of a plurality of thin laminated transparent layers.

    摘要： When a separation layer is formed using a stamper between a substrate and the stamper on a thick substrate, on the surface of which a rewritable recording multilayer film provided with signal guide grooves or pits and the signal guide grooves or pits are transferred from the stamper to the surface, variations in the thickness of the separation layer are produced due to unevenness of the distance between the stamper and the substrate.The surface of the kth signal recording layer of the kth signal substrate is shaped parallel to the surface with the guide grooves and pits of the (k−1)th signal recording layer on the (k−1)th stamper, a (k−1)th separation layer is formed between the two and then the (k−1)th stamper is peeled off. The distance between the surface with the guide grooves and pits of the (k−1)th signal recording layer and the kth signal recording layer becomes uniform, and therefore the thickness of the (k−1)th separation layer can be kept uniform.

    摘要： An optical disk is manufactured by bonding a resin stamper having, on a principal plane, asperity pits on which a thin film is formed and a second substrate having a thickness of 0.3 mm or less with radiation cured resin such that the asperity pits face to the second substrate. The resin stamper is peeled off after curing the radiation cured resin to form asperity pits on the second substrate. A metal film is formed on the asperity pits on the second substrate to attain an information recording layer on the second substrate. A first substrate having an information recording layer and the second substrate having the formed information recording layer are bonded such that the both information recording layers face each other.

    摘要： An optical disc manufacturing method suppresses thickness variation in intermediate layers disposed between any two data recording layers to achieve an intermediate layer of uniform thickness. A substrate having a center hole and data recording layer is first prepared. This center hole is then plugged with a capping member and a resin material is dripped from above the center hole while spinning the substrate around its center hole to coat the data recording layer with the resin by a spin coating method. The capping member is then removed. Then, a stamper having a groove or lands and pits on its surface is prepared. The groove or lands and pits side of the stamper is then pressed into the resin material on the substrate, and the resin is then cured to form an intermediate layer. The stamper is then separated from the substrate to leave a data recording layer in the surface of the intermediate layer with a groove or land-and-pit pattern corresponding to the groove or lands and pits in the stamper.
