Laser power control method of optical recording/reproducing apparatus

A method for controlling laser power of an optical recording/reproducing apparatus, comprising steps of:

• performing a writing procedure with an initial electric power level supplied to a laser module of said optical recording/reproducing apparatus;
• generating a first triggering signal at a first predetermined time point during said writing procedure;
• performing an optimum power calibration (OPC) procedure to determine a first optimum electric power level in response to said first triggering signal;
• and
• performing said writing procedure by replacing said initial electric power level with said first optimum electric power level supplied to said laser module of said optical recording/reproducing apparatus.

A method for controlling laser power of an optical recording/reproducing apparatus, comprising steps of:

• performing a first writing procedure with an initial electric power level supplied to a laser module of said optical recording/reproducing apparatus;
• performing an optimum power calibration (OPC) procedure to determine a first optimum electric power level if a temperature change of said optical recording/reproducing apparatus under said initial electric power level is larger than a threshold value;
• generating a triggering signal at a predetermined time point;
• performing another optimum power calibration (OPC) procedure to determine a second optimum electric power level in response to said triggering signal;
• and
• performing said writing procedure by replacing said initial electric power level with said first or second optimum electric power level, whichever occurs earlier, and supplying the new optimum electric power level to said laser module of said optical recording/reproducing apparatus.
