OPTICAL RECORDING MEDIUM, METHOD FOR MANUFACTURING THE OPTICAL RECORDING MEDIUM, REPRODUCTION SIGNAL PROCESSING METHOD AND EVALUATION METHOD |
摘要 |
An optical head 12 reproduces information recorded on an optical disc 11, a BCA detector 21 and a medium discriminating circuit 22 acquire waveform distortion information for specifying a waveform distortion of a reproduction signal reproduced by the optical head 12, and a variable waveform equalizer 16 changes a parameter used in a distortion reduction processing for reducing the waveform distortion of the reproduction signal based on the waveform distortion information.
