Abstract: An information recording medium according to the present invention includes three or more information recording layers. Each of the plurality of information recording layers includes a test recording area usable for adjusting a recording condition. One of the plurality of information recording layers includes a reproduction-only management data area in which management data usable for managing the information recording medium is pre-recorded. One information recording layer includes a recordable management data area in which management data usable for managing the information recording medium is newly writable. Each of the other two or more information recording layers among the plurality of information recording layers includes a test recording area at a radial position overlapping the radial position of a part of the reproduction-only management data area. In the one recording layer including the recordable management data area, the recordable management data area is provided at two positions, i.e.
