Abstract
An information recording medium is provided, which comprises a plurality of recording layers and a first disc information area for storing parameters relating to access to the plurality of recording layers and formats relating to the plurality of recording layer. The first disc information area is provided in a first recording layer which is one of the plurality of recording layers.
Claims3
An information recording medium, comprising:
- a plurality of recording layers;
- and
- a disc information area in which disc information relating to the plurality of recording layers are stored,
- wherein the disc information area is provided in a first recording layer which is one of the plurality of recording layers and a second recording layer which is another one of the plurality of recording layers,
- a dummy data is recorded in a remaining area of the disc information area, and
- a length of an area for storing the dummy data is an integer multiple of a length of the disc information area.
A recording/reproduction apparatus for performing at least one of recording information into an information recording medium and reproducing information from the information recording medium, wherein
- the information recording medium comprises:
- a plurality of recording layers;
- and
- a disc information area in which disc information relating to the plurality of recording layers are stored,
- wherein the disc information area is provided in a first recording layer which is one of the plurality of recording layers and a second recording layer which is another one of the plurality of recording layers,
- a dummy data is recorded in a remaining area of the disc information area, and
- a length of an area for storing the dummy data is an integer multiple of a length of the disc information area,
- the recording/reproduction apparatus comprises:
- an optical head capable of performing at least one of optically writing the information into the information recording medium and optically reading the information from the information recording medium;
- and
- a control section for controlling a recording/reproduction process using the optical head, and
- wherein the recording/reproduction process comprises:
- reproducing the disc information stored in the disc information area;
- and
- at least one of recording the information into the information recording medium and reproducing the information from the information recording medium, based on the reproduced disc information.
A recording/reproduction control apparatus for performing at least one of a recording information into an information recording medium and reproduction information into an information recording medium and reproducing information from the information recording medium, wherein
- the information recording medium comprises:
- a plurality of recording layers;
- and
- a disc information area in which disc information relating to the plurality of recording layers are stored,
- wherein the disc information area is provided in a first recording layer which is one of the plurality of recording layers and a second recording layer which is another one of the plurality of recording layers,
- a dummy data is recorded in a remaining area of the disc information area, and
- a length of an area for storing the dummy data is an integer multiple of a length of the disc information area,
- the recording/reproduction control apparatus comprises:
- reproducing the disc information stored in the disc information area;
- and
- at least one of recording of the information into the information recording medium and reproducing the information from the information recording medium, based on the reproduced disc information.
