Patent ID: 8139465

Claim:
An information recording apparatus comprising: a recording device for recording information onto an information recording medium by irradiating the information recording medium with a recording laser beam whose power can be adjusted; a controlling device for controlling the recording device to record calibration data by irradiating the information recording medium with the recording laser beam in which the power is adjusted gradually; a detecting device for detecting returned light from the information recording medium of the recording laser beam irradiated by the control of the controlling device; an ending device for ending the irradiation of the recording laser beam by the control of the controlling device in a case where amount of the returned light detected by the detecting device exceeds a predetermined range; and a determining device for determining an optimum power for recording the information, on the basis of a reproduction signal obtained by reading the calibration data after the irradiation of the recording laser beam is ended by the control of the ending device, wherein the case where the amount of the returned light detected by the detecting device exceeds the predetermined range is a case where a push-pull signal estimated from the returned light detected by the detecting device exceeds a reading limit level of the push-pull signal.
