An information recording medium (100) is provided with a first recording layer (L0 layer) and a second recording layer (L1 layer), which have user data areas (105, 115) for recording user data and record managing areas (103, 113) for recording record managing data, respectively. An information recording device (200) records user data and the record managing data in the information recording medium. The information recording device is provided with a recording means (352), which divides the record managing area into a plurality of record managing segments and records the record managing data in one of the record managing segments, and a first control means (354) for controlling the recording means so that each of the record managing segments is arranged in a single recording layer.
