摘要： In the method of manufacturing an optical recording medium according to the present invention, when an optical recording medium having at least first and second minute concave and convex surfaces formed thereon is manufactured, the first and second minute concave and convex surfaces are simultaneously molded on both surfaces of a substrate of the optical recording medium. Therefore, it is possible to manufacture a multilayer optical recording medium having an excellent symmetrical structure with respect to a vertical cross section direction of the substrate, i.e., in the thickness direction of the optical recording medium. Moreover, it is possible to effectively suppress the deformation thereof resulting from curing or shrinkage of an light curing resin or the like, absorption or removal of vapor in the air into or from a substrate, a transparent intermediate film or the like, and so on.

摘要： A method of forming a protective film for an optical recording medium. A protective film forming ink having a viscosity in a range between 0.9 and 100 ps is applied on a surface of a pad, e.g., a semispherical pad, having a Shore A hardness between 8 and 30. The spherical surface of the pad thus applied with the ink is pressed to a substrate of the optical recording medium on which a reflective layer is formed to transfer the protective film forming ink to the surface of the substrate so as to cover the entire surface of the reflective layer and extend over the peripheral edges. Then, the ink is cured to form the protective film.

摘要： An optical disc substrate having a reduced thickness and sufficient rigidity is provided which can be of a single-plate structure. It can be compatible with a magneto-optic recording and also with a conventional disc driving means. The substrate consists of a disc supporting portion (21) formed around the center of the substrate and of which one side (21a) provides a surface at which the disc is to be mounted on a disc driving means, and a recording portion (22) formed between the disc supporting portion (22) and a circumference of the substrate and of which one side (22a) provides a recording surface. The disc supporting portion (21) is designed thicker than the recording portion (22) so that the disc supporting surface (21a) and the recording surface (22a) will not lie together in a sample plane. A recess 25 may be formed between the recording portion (22) and disc supporting portion (21), and also a projection (27) may be formed along the circumference of the side (22b). Furthermore, one or more functional layer may be formed on the side (22b) opposite to the recording surface.
