    摘要: A method of manufacturing a multilayer optical recording medium fabricates a first stamper made of metal and a resin stamper in which a fine protrusion/depression pattern is formed, the fine protrusion/depression pattern of the resin stamper being formed by transferring a pattern from a metal stamper, being deeper than a reversed fine protrusion/depression pattern of the first stamper, and being capable of forming, in one surface of a spacer layer, guide grooves of equal depth to guide grooves formed in one surface of a substrate. By transferring a pattern from the first stamper, the substrate that has guide grooves formed in one surface is fabricated. A recording layer is formed on a surface of the guide grooves of the substrate and a light transmitting resin is applied onto the surface of the recording layer. A pattern is transferred from the resin stamper to the surface of the light transmitting resin to form the spacer layer in which guide grooves of equal depth to the guide grooves formed in the substrate are formed, and the recording layer is formed on the surface of the guide grooves of the spacer layer.

    摘要: A method for manufacturing a multilayer recording type optical recording medium and an intermediate in a manufacturing process of the optical recording medium are provided, which can form a spacer layer and a light transmitting layer with a uniform thickness and can provide good production efficiency. In this manufacturing method, a circular projection having an outer diameter smaller than an inner diameter of a central hole is formed near the center of the spacer layer. The light transmitting layer is spread on the spacer layer by supplying a radiation curable resin to a region around the circular projection and rotating the substrate. The light transmitting layer is irradiated with radiation to be cured. Then, the central hole is formed, thereby removing the circular projection.

    摘要: An optical recording medium of phase change type, and in particular, a dual side medium prepared by adhering two single side media is provided. In this medium, deformation of record marks generated in the overwriting due to difference in light absorption between the record marks and the region other than the record marks is prevented by providing a reflective layer of high light transmission, and increase in jitter and failure of track servo and focus servo caused by uneven coating of the adhesive layer and the resin protective layer are prevented. The optical recording medium comprises a substrate, a recording layer of phase change type on the surface side of the substrate, and a reflective layer and a light absorption layer disposed in this order on the surface side of the recording layer. The light absorption layer has a light transmission of 85% or higher in wavelength range S (wavelength in the range of 400 to 450 nm), up to 55% at the recording/reproducing wavelength, and 80% or higher in wavelength range L (wavelength in the range of 800 to 830 nm).
