Abstract:
A method for determining an optimum laser power for a recording medium. The method includes checking if a portion of an unused area in a test area on the recording medium is defective, and performing an optimum laser power operation in a used area in the test area, in which the used area is a non-defective area that was used to test the optimum laser power for the recording medium.
