摘要: An optical information recording medium reproducing device ( 1 ) reproduces from a super-resolution 100 having the stored therein by positioning, according to random pattern system, plurality of marks including mark shorter than resolution limit an system. This performs test readings for measuring indexes each relating reproduction quality emitting laser light onto storage surface ), while changing power predetermined initial value, and based on measured, sets information. Thus, since in is determined results, favorable can be obtained.
