Information recording/reproducing method and apparatus using EPRML connection processing system

摘要

An information recording/reproducing apparatus includes first and second data demodulators having different data discriminating capabilities. The first data demodulator has a lower data discriminating capability and the second data demodulator has a higher data discriminating capability. When the reliability of reliability information for demodulation data generated by the first data demodulator, the second data demodulator is operated so that demodulation data generated by the first data demodulator is replaced by demodulation data generated by the second data demodulator during a period of time when the reliability of the reliability information is deteriorated.
