| Abstract | Methods and apparatuses for controlling optical storage appliances which allow a signal to be obtained even in areas of the recording media in which there is no contrast, whose phase angle with respect to a tracking error signal indicates the movement direction of an actuator relative to the tracks and the track type. A weighting factor is set from the focus error signals from the main and secondary scanning beam, and a suitable track type signal is obtained. |
