    摘要: In an information recording medium including at least a first recording layer (L0 layer) capable of recording information and a second recording layer (L1 layer) capable of recording information, an information recording device (300) records information in a predetermined area (12) of the second recording layer by a laser beam which has passed through a transmission area (11) of the first recording layer. The information recording medium (300) includes recording means (302, etc.) for recording the information in the first recording layer or the second recording layer, judgment means for judging whether an unrecorded amount indicating the size of the unrecorded area in the radial direction in the transmission area is smaller than a predetermined amount, and control means used when the unrecorded area is judged to be smaller than the predetermined amount, for controlling the recording means to record information in the predetermined area.
