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.
Claims25
A method for determining an optimum laser power for a recording medium, the method comprising:
- 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, said used area being a non-defective area that was previously used to test the optimum laser power for the recording medium.
An apparatus for determining an optimum laser power for a recording medium, the apparatus comprising:
- a pickup unit configured to record data on the recording medium and to read data from the recording medium;
- and
- a controller configured to check if a portion of an unused area in a test area on the recording medium is defective, and to perform an optimum laser power operation in a used area in the test area,
- wherein the used area is a non-defective area that was previously used to test the optimum laser power for the recording medium.
A system for determining an optimum laser power for a recording medium, the system comprising:
- means for checking if a portion of an unused area in a test area on the recording medium is defective;
- and
- means for performing an optimum laser power operation in a used area in the test area, said used area being a non-defective area that was previously used to test the optimum laser power for the recording medium.
