摘要：
An information recording apparatus (1) is provided with: a recording device (102) for recording information onto an information recording medium (100) by irradiating the information recording medium with a recording laser beam (L); a controlling device (103) for recording calibration data onto the information recording medium by using the recording laser beam in which the power is adjusted gradually; and a detecting device (107) for detecting degree of modulation of a reproduction signal after the recording of the calibration data, the recording of the calibration data being ended if the degree of modulation exceeds a predetermined range, an optimum power of the recording laser beam being determined from a jitter amount included in a reproduction signal.
