Abstract

An information recording medium is provided with: a first recording layer (L0) to record therein first information; and one or a plurality of second recording layers (L1 etc.) which are laminated on the first recording layer and each of which is to record therein second information, each layer of the second recording layers having a predetermined area (PCA1-1) where power calibration is performed to detect an optimum recording power of laser light for recording, which is transmitted through another layer of the second recording layers located on a closer side to first recording layer than the each layer and through the first recording layer, in an opposite area (TA) facing the predetermined area in the another layer and the first record layer, a first parameter which constitutes the opposite area being changed, to thereby cause light transmittance of the opposite area to approach light transmittance under an assumption that the first parameter is not changed and that the another layer and the first record layer are recorded, as compared to light transmittance under an assumption that the first parameter is not changed and that the another layer and the first record layer are unrecorded.
