A METHOD AND APPARATUS FOR CONTROLLING LASER POWER FOR A PLURALITY OF LASER BEAMS |
摘要 |
A method of controlling laser power for a plurality of laser beams, the method comprising the steps of: - successively switching on (710) the writing of each laser beam at different starts of segment for writing data, - successively switching off (720) the writing of each laser beam that arrives at the start of a segment previously written by another laser beam, - detecting (730) only one laser beam that has kept on writing, - calibrating (732) laser power of the only one laser beam, - switching off (750) the writing of said only one laser beam, and - shifting (760) all laser beams. |
