摘要： Optical information recording is achieved at high speed such as sixthfold to eightfold speed of DVD while suppressing jitter by a high-speed recording strategy such as a 2T period strategy, by once reducing the optical power of the optical beam used for optical recording, when starting recording of an amorphous mark pattern after the step of forming a crystalline space region but before the step of irradiating the optical beam with a peak power level for the mark formation, such that the optical power of the optical beam is reduced below the erasing optical power used for forming the crystalline space region.
