Patent ID: 7212473

Claim:
A method for reproducing an optical disc, comprising the steps of: a) detecting, for a predetermined period of time, a level of a tracking error signal outputted when the optical disc is driven; b) comparing the level of the detected tracking error signal with a predetermined reference level; c) setting that a current focus point of an objective lens for the optical disc is optimized without adjusting a focus bias of the objective lens, if the comparing step (b) indicates that the level of the detected tracking error signal is not lower than the predetermined reference level; d) carrying out an operation of adjusting the focus bias of the objective lens arranged within an optical pickup on the basis of the detected level of the tracking error signal, if the comparing step (b) indicates that the level of the detected tracking error signal is lower than the predetermined reference level; and e) setting a focus bias adjustment value as an optimum focus bias value at a time when the detected level of the tracking error signal is maximized after performing the step (d).
