  • Patent number: 8411538
    Abstract: In an optical information storage medium reproduction apparatus (10) for reproducing an optical information storage medium including a plurality of information recording layers each including a recording mark having a length shorter than an optical system resolution limit, reproduction laser power for reading an information recording layer closest to a reproduction-laser-incident surface of the optical information storage medium is set to be lower than reproduction laser power for reading an information recording layer farthest from the reproduction-laser-incident surface but not lower than minimum reproduction laser power that satisfies a reproduction signal characteristic that the optical information storage medium reproduction apparatus (10) requires.

  • Patent number: 8379505
    Abstract: A super-resolution optical recording medium includes: a medium information region on which medium identification information is recorded; a content region on which content information is recorded; and a blank region provided between the medium information region and the content region and in which at least two tracks are provided so as to connect a train of prepits in the medium information region and a train of prepits in the content region. No information is recorded on the blank region. Thus, a super-resolution optical recording medium is provided in which a region on which medium identification information is recorded and a region on which content information is recorded are different in track pitch and in which a reproduction error hardly occurs when reproduction shifts from the region on which the medium identification information is recorded to the region on which the content information is recorded.

  • Publication number: 20120327755
    Abstract: Disclosed is an information recording medium which, when inserted into a recording/reproducing device, can be run in an updated state intended by a disc supplier since a recordable layer can be specified as a layer to be run first. For example, in an optical disc including an L1 layer which is a read-only recording layer and an L0 layer which is a recordable layer, layer specifying information for specifying the L0 layer in priority to the L1 layer is recorded as an information recording layer to be run first when the optical disc is inserted into the optical disc device which carriers out recording or reproduction of information with respect to the optical disc.
