INFORMATION REPRODUCING DEVICE, SIGNAL PROCESSOR, INFORMATION REPRODUCING METHOD AND OPTICAL RECORDING MEDIUM |
摘要 |
PROBLEM TO BE SOLVED: To provide an information reproducing device which is capable of eliminating the crosstalks from adjacent tracks even in wobbble signals, a signal processor, an information reproducing method and an optical recording medium. SOLUTION: This information reproducing device has a detector 152 which outputs the difference between the individual output signals optically obtainable from a pair of detectors for reading the information of the first track MT, a detector 151 which outputs the difference between the individual output signals optically obtainable from a pair of detectors for reading the information of the second track ST1, a demodulating section 202 which demodulates the detection signal outputted from the detector 152 and a demodulating section 201 which demodulates the detection signal outputted from the detector 151. A coefficient control section 205 extracts the crosstalks derived from the second track ST 1 included in the demodulation signal obtained by the demodulating section 202 and controls a coefficient in accordance with the extracted crosstalks. A crosstalk control section 205 cancels the crosstalks by the calculated coefficient.
