    摘要： An information recording medium is provided that includes a data area for recording user data and a defect management area for recording a defect list for managing N number of defect areas existing in the data area, where N is an integer satisfying N≧0. The defect list includes two or more blocks, and further includes a header located at a fixed position in the defect list and N number of defect entries, located subsequent to the header, including position information on the respective positions of the N number of defect areas. An anchor is located subsequent to the defect entries, and the header includes first update times information representing the number of times that the defect list has been updated. The anchor includes second update times information representing the number of times that the defect list has been updated.

    摘要： On a recording medium, data is recorded on at least one of a plurality of recording layers by laser light incident on a surface of the recording medium. The plurality of recording layers include a first recording layer, and second through N-th recording layers (N is an integer of 3 or greater) which are sequentially located in a direction from the first recording layer toward the surface on which the laser is incident. The plurality of recording layers each have a first calibration area and a second calibration area located outer to the first calibration area. The first calibration area located in each of the first through N-th recording layers is located at a different radial position from a radial position of the first calibration area in each of the other recording layers; and the second calibration area located in each of the first through N-th recording layers is located at the same radial position as a radial position of the second calibration area in each of the other recording layers.

    摘要： OPC areas are used for adjusting recording parameters (power and strategy). In an optical disc including two recording layers, the recording power for one recording layer is likely to be influenced by a transmittance variance or the like provided by the recording state of the other recording layer (either already recorded or unrecorded). In addition, recording is performed while changing the power. For these reasons, the OPC areas are located so as not to be at the same radial positions among the recording layers. However, as the number of recording layers is increased, the area size for securing the OPC areas is increased, which may undesirably lead to an increase of the lead-in zone or the lead-out zone (decrease of the user data zone) and a decrease of the OPC area size in each recording layer (decrease of the number of times of usage by the user). According to the present invention, an area for power calibration in which recording is performed while changing the power and so which is significantly influenced by the transmittance balance, is separated from an area for strategy calibration or the like in which recording is performed at a fixed power suitable to the disc and so which is unlikely to be influenced by the transmittance balance. Only power calibration areas are located at different radial positions among different recording layers so as not be influenced by the recording state of the other recording layers, and the strategy calibration areas are located so as to include the same radial position among different recording layers.
