ABSTRACT:
At ST1,the process identifies whether apparatus identification information of an optical recording apparatus is recorded in an optical recording medium and, if it is not recorded, if the recorded information does not agree with apparatus identification information of the optical recording apparatus, or if they agree but information validation conditions are not met, it performs processing of ST2and ST3to perform power calibration processing of laser light and calculate power set values. At ST4,the process records power calibration information and the apparatus identification information in the recording medium. If the information agrees and the information validation conditions are met, the process performs processings of ST9and ST10to calculate power set values using already created information. At ST5,the process sets laser light power based on the power set values. If a recording medium, which has once been used, is used, recording of a signal can start immediately in a condition where the laser light power is optimized.
