Patent ID: 7539113

Claim:
An information recording apparatus for recording record information onto an information recording medium comprising: a first recording layer on which the record information is recorded by irradiating thereon laser light; and a second recording layer on which the record information is recorded by irradiating thereon the laser light through the first recording layer, said information recording apparatus comprising: a recording device for recording the record information into the first recording layer or the second recording layer by irradiating thereon the laser light, the recording device recording the record information into the second recording layer after the recording device records the record information into the first recording layer, the record information being recorded from an inner circumferential side to an outer circumferential side in the first recording layer and the record information being recorded from an outer circumferential side to an inner circumferential side in the second recording layer; a first controlling device for controlling said recording device to record the record information into a first object area which is a recording area of the second recording layer which is irradiated with the laser light passing through a recorded area of the first recording layer in which the record information is already recorded; and a second controlling device for controlling said recording device to record the record information into a second object area which is a recording area of the second recording layer which is irradiated with the laser light passing through an unrecorded area smaller than a predetermined width, out of an unrecorded area which are adjacent to the recorded area, wherein the recording device records control information into the unrecorded area after the recording of the record information into the second recording layer is ended.
