ABSTRACT:
A method for determining an optical write power and an optical disc access system using the same. In addition to a typical Inner Power Calibration Area, the method includes an Outer (second) Power Calibration Area implementation on the outer area of a Readable/Writable Optical disc with a constant linear velocity (CLV) format; when a data writing speed selected by a user causes a rotation speed required by an optical power calibration on an Inner (first) Power Calibration Area of the disc greater than an Optical Power Calibration (OPC) limit, the optical disc access system uses a lower rotation speed for the optical power calibration on the Outer Power Calibration Area to ensure the accuracy of the power calibration.
