摘要 |
<p>An information playback apparatus (200) of the present invention is provided with: a first detecting unit (152) for supplying a difference between respective output signals optically obtained by a pair of detectors for reading the information of the first track (MT); a second detecting unit (151) for supplying a difference between respective output signals optically obtained by a pair of detectors for reading the information of the second track (ST1) adjacent to the first track (MT); a first demodulating unit (202) for demodulating a detected signal supplied from the first detecting unit (152), a second demodulating unit (201) for demodulating a detected signal supplied from the second detecting unit (151). A coefficient controlling unit (205) extracts the crosstalk caused by the second track (ST1), which is included in a demodulation signal obtained by the first demodulating unit (202), from the same signal and controls a coefficient based on the extracted crosstalk, and cancels the crosstalk by the calculated coefficient. <IMAGE></p> |
