In an optical disk player including a focus servo system (17,18) for forming a data detection light spot on a recording disk (7) and a tracking servo system (19,20) for producing a tracking error signal to control the position of the light spot relative to a recording track (8), an address search method is employed 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 during 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 is then recommenced.
