| Zusammenfassung: | The information recording medium (1) of the present invention has a track for recording information. The track is composed of a groove portion (2) and a land portion (3). The groove portion (2) has a synchronous structure where wobbles (2a, 2b) on both sidewalls of the groove are not shifted from each other in the circumferential direction (in the drawing, the vertical direction). The wobbles on both sidewalls of the land of the land portion (3) constitute an asynchronous structure. Favorable reproduction signals can be generated from the groove portion (2) and the land portion (3). |
