Record conditional optimization method, information record reproducing arrangement, integrated circuit device and record conditional optimization program

摘要

It decreases the influence of optical quality and playback transmission line quality of the optical head to the utmost, it designates that more appropriate record condition is adjusted as purpose. As for record conditional optimization method of this invention, the optical disk (100) information the case where it records being the method of optimizing record condition, making use of the waveform equalization quality which is set the equalization quality setting process which sets waveform equalization quality the playback process which plays back the record pattern which is recorded the record process which records the record pattern which includes the plural record marks making use of specified record condition, to the optical disk (1103) with, record process (1103) in (1102) with, according to record pattern (1101) with, equalization quality setting process (1101) by, playback process (1102)The adjustment process which adjusts record condition making use of the regenerative signal which is equalized the equalization process which the regenerative signal which it played back the ripple mark is equalized (1105) with, equalization process (1105) with the ripple mark, (1104) with it has.
