Optical information recording method and optical information regeneration recorder, and signal processing circuit, and recording reproduction program and information recording medium

摘要

An optical information recording method in an optical recording generation method for performing recording and reproduction of information by radiating laser light which is pulse-modulated according to a recording waveform having a plurality of setting parameters onto a storage medium is disclosed. The method comprises reading information recorded in the storage medium; determining positions corresponding to a detection pattern from the detection pattern and a reproduction signal, the detection pattern being defined according to a specific parameter from among the plurality of setting parameters, and the reproduction signal being obtained by reading the information; detecting the state of the reproduction signal according to the result of the determination; generating an ideal reproduction signal according to the detection pattern; and obtaining a predetermined signal evaluation index value using the result of detection of the state of the reproduction signal and the ideal reproduction signal.
