Abstract: We have developed a cross-talk canceller for a wobbling signal (WCTC). The WCTC cancels cross-talk in the wobbling signal using three push-pull signals reproduced from three adjacent tracks. Furthermore, push-pull tracking offset, caused by a shift of an objective lens, is detected from a balance between cross-talk from an inner track and that from an outer track. It is experimentally confirmed that the WCTC effectively reduces cross-talk and can detect the tracking offset.
