| 20100110850 | INFORMATION RECORDING MEDIUM, INFORMATION RECORDING METHOD AND INFORMATION RECORDING APPARATUS - 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.
