Recording medium and reproducing device thereof

摘要

The data recorded on an optical disk (11) is read by an optical pickup (21). After the thus obtained signal has been subjected to a waveform equalization process at a waveform equalizer (23), it is demodulated via a data slicer (24). A parameter for obtaining a waveform equalization characteristic best suited for reading the recorded data has been recorded on the optical disk (11). The demodulated parameter is decoded by a data processor (29). The data processor (29) switches the waveform equalization characteristic of the waveform equalizer (23). <IMAGE>
