ABSTRACT:
A tracking error signal is detected using an error detector, from cross-talk components at a point in each of the regions of several duplication areas from which reproduction is possible, and tracking control is performed using a servo circuit, based on the average value of the error signals or the average of the maximum and minimum of the peak values of the error signals from the respective areas during one scan. Even when a large amount of fast playback data is recorded, and track non-linearity is present, the fast playback can be reproduced without fail, and signals in fast playback data regions at a plurality of locations can be obtained without fail.
