ABSTRACT:
In an optical disk player including a focus servo system for forming a data detection light spot on a recording disk and a tracking servo system for producing a tracking error signal to control the position of the light spot relative to a recording track, an address search method is provided in which the movement of the light spot is controlled according to a track pulse formed according to the level of the tracking error signal. When it is determined that no track pulse has been produced for a predetermined period of time, the track jumping operation of the light spot is suspended and the abnormal condition of the focus servo system corrected. Track jumping can then be recommenced.
