ABSTRACT:
A method for determining optimum write power for an optical disc in an optical disc recording apparatus includes, test writing the optical disc as a recording medium at a first position where a write sensitivity is higher than an average write sensitivity of the optical disc and at a second position where the write sensitivity is lower than the average write sensitivity by the same amount of difference as the difference between the write sensitivity at the first position and the average write sensitivity, using the same write power to the both of the first position and the second position, and obtaining an optimum write power for the optical disc from an average of a write characteristics of the test written positions.
