In an information recording medium comprising at least a substrate, a recording layer, and a resin layer, the substrate is formed with at least a pit corresponding to a read only area (31) and a groove corresponding to a recording/reproducing area (32) without overlapping with each other. A reflectivity of the recording layer is specified to be more than 10 %. The recording layer and the resin layer are continuously adhered over both the read only and recording/reproducing areas (31 and 32). The information recording medium is characterized in that both push-pull signal outputs T1 and T2, which are reproduced from the read only area (31) and the recording/reproducing area (32) respectively, are more than 0.1 and satisfy an inequality 1.5 ‰§ T1/T2 ‰§ 0.5. |
