Patent ID: 7023772

Claim:
A laser power setting method comprising: a first identification step for identifying whether apparatus identification information assigned to an optical recording apparatus is recorded in an optical recording medium, said apparatus identification information being unique to the optical recording apparatus; a second identification step for identifying whether said apparatus identification information recorded in said optical recording medium, if it is identified that said apparatus identification information has been recorded in said first identification step, agrees with said apparatus identification information unique to said apparatus; a first processing step for performing first processing when a first identification result is obtained which includes a result of a case where it is identified in said first identification step that said apparatus identification information is not recorded and a result of a case where it is identified in said second identification step that said recorded apparatus identification information does not agree with said apparatus identification information assigned to said optical recording apparatus; and a second processing step for performing second processing under at least one condition that a second identification result is obtained, said second identification result including a result of a case where it is identified in said first identification step that said apparatus identification information is recorded and a result of a case where it is identified in said second identification step that said recorded apparatus identification information agrees with said apparatus identification information assigned to said optical recording apparatus, wherein said first processing step includes a creation step for creating power calibration information by performing power calibration processing and a first setting step for setting laser light power based on the power calibration information created in said creation step; and wherein said second processing step includes a second setting step for setting laser light power based on the power calibration information recorded in said optical recording medium.
