    摘要: An optical recording medium is formed by applying a coating liquid to form a light-reflecting layer on a substrate having a surface provided with a pre-format pattern comprising a concavity and a convexity. The concavity is designed to have a sectional shape of a trapezoid having a pair of parallel opposite sides, a shorter one of which constitutes the bottom of the concavity, and a pair of sloping sides. Each sloping side forms a (solid part) angle .theta. of not larger than 35 degrees with respect to the extension of the substrate surface. The concavity has a depth d larger than .lambda./4n wherein .lambda. is the wavelength of an optical radiation beam with which the optical recording medium is illuminated for recording and/or reproduction and n is the refractive index of the substrate.

    摘要: An optical information medium having an ink-accepting layer that may secure a high-gloss printed surface similar to print image quality of print image on photographic paper is provided. The optical disk 1 is constituted by sequentially laminating concavo-convex information pits 3, a recording layer 4, a reflective layer 5, a protective layer 6, a second printing layer 7, and an ink-accepting layer 8 on a transparent substrate 2 made of synthetic resin such as polycarbonate. In the formation of the ink-accepting layer 8, the following proportions of the following constituents in percent by weight are milled to prepare an ink for printing: 5 to 15% urethane acrylate; 70 to 80% water-soluble monomer; 5 to 15% water-soluble monomer soluble resin; 5 to 15% photopolymerization initiator; 5 to 15% dyestuff fixing agent; and
