Abstract
The recording condition setting device according to the present invention includes (i) a specific pattern detection circuit for detecting, as a specific pattern, one or more patterns having been set by recording information, from one or more decoded bit sequences generated from a reproduction signal received from an optical disc, (ii) a path metric difference classification circuit for classifying one or more specific path metric differences into one or more by-recording-information path metric differences corresponding to one or more by-recording-information patterns, said specific path metric differences being obtained by extracting one or more path metric differences corresponding to the detected specific patterns from path metric differences generated from the reproduction signal, and (iii) a recording condition setting circuit for setting the recording condition based on the classified by-recording-information path metric differences.
