摘要： An optical disc recording medium includes a disc substrate, at least one recording layer which is disposed on one surface side of the disc substrate, a cover layer which is disposed on a laser incident surface side of the recording layer and which is composed of a light-transmissive resin layer, and a hard coat layer which is disposed for surface protection on a laser incident surface side of the cover layer and which is composed of a light-transmissive resin layer. The cover layer is formed such that its thickness decreases from the central portion to the peripheral portion of the disc, the hard coat layer is formed such that its thickness increases from the central portion to the peripheral portion, and the total thickness of the cover layer and the hard coat layer is substantially uniform from the central portion to the peripheral portion.

摘要： Provided is a method of producing an optical disc recording medium with which an inexpensive optical disc recording medium can be produced.For this purpose, the method of producing an optical disc recording medium of the present invention includes the steps of preparing a transfer substrate; forming an ultraviolet-curable resin layer on a surface of the transfer substrate; forming a projection-and-recess pattern on the ultraviolet-curable resin layer by pressing a nickel stamper having a desired projection-and-recess pattern onto the ultraviolet-curable resin layer under pressure while performing ultraviolet irradiation from the reverse surface side of the transfer substrate, and forming a recording layer on the ultraviolet-curable resin layer on which the projection-and-recess pattern is formed, wherein recording layers are formed in descending order of the light transmittance.
