Recording/reproducing device including recording parameter setting device, and nontransitory computer-readable medium storing program for causing computer to operate as the same

摘要

A recording parameter setting device includes a trial recording parameter setting section and a reproduced signal quality judging section. The trial recording parameter setting section sets a trial recording parameter capable of controlling a heat level at least rear edges of recording marks, classified in accordance with recording mark lengths, and grouping a predetermined recording mark length or longer into a same group. The reproduced signal quality judging section judges whether a trial recording carried out in accordance with the trial recording parameter satisfies a predetermined reproduced signal quality. If the signal quality is unsatisfactory, the trial recording parameters of the predetermined recording mark length or longer are regrouped and trial recording is carried out again until the reproduced signal satisfies the predetermined signal quality. Then, the reproduced signal quality judging section sets the trial recording parameter as the recording parameter.
