<P>PROBLEM TO BE SOLVED: To acquire a simple and highly precise information recording method by correcting a control error between a setting value of recording power and the recording power caused by decreasing of sensing light quantity by optical phase difference of an optical disk. <P>SOLUTION: In the information recording method of an information recording/reproducing apparatus which performs recording and reproducing of information to the optical disk using a semiconductor laser, either a calculated value of optimal recording power in performing recording of information is corrected or a target value of recording power in the state of recording the information is corrected based on a detected value of the optical phase difference of the optical disk. Also, when calculating the optimal recording power before a start of recording information to the optical disk, a calculation value of optimal recording power Pwo is obtained by using an optimal index value (β value) which is correction of an optimal index value indicating the optimal recording power based on a detection value of an optical phase differential of the optical disk against a prescribed primary index obtained by reproducing a test writing area which records by gradually changing the recording power. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
