An apparatus and method for detecting the optimal writing power of an optical disc

The present invention relates to the optimum recording optical power detector and detection method for aging the optical disc, to the optimum recording optical power detection method for aging an optical disc according to the present invention, it reads out the recorded signal of the insert seating rewritable optical disc player first step; A second step for outputting to equalize the level of the high-frequency reproducing signal read out the reproduction; A third step of using the high-frequency reproducing signal and / or based on the the equalized reproduction signal determines whether the optical disk is aging; And in the case by the third step on which the optical disk is determined as the aging disc, made by from the test region of the optical disc includes a fourth step of performing the OPC operation several times, using as a data overwriting (Overwrite) several times aging disc la also very useful inventors that by so that the recording operation performed by the optimum recording optical power, and improve the reproduction characteristic of the recorded data even.
