  • Optical information recording medium and method for producing the same
    Patent number: 6447869
    Abstract: An optical information recording medium includes a first substrate; at least a first dielectric layer and a recording layer for signal recording provided on a surface of the first substrate; and a second substrate. The first substrate and the second substrate are assembled together in the state of being warped in planar symmetry and flattened. The first dielectric layer and the recording layer is interposed between the first substrate and the second substrate.
    Type: Grant
    Filed: April 24, 2001
    Date of Patent: September 10, 2002
    Assignee: Matsushita Electric Industrial Co., Ltd.
    Inventors: Eiji Ohno, Hidemi Isomura, Akihiro Moteki
