Abstract
The present invention relates to a modulated signal generator capable of carrying out signal processing at a higher speed or capable of supporting a special format and a new format with ease. A modulation processing storing unithas a modulation processing program required for producing an optical disc masterstored therein in advance. Information data recorded in an master optical discis reproduced by an information reproducing unitand is outputted to a modulation controller. The modulation controllercarries out the signal modulation processing onto the reproduced information data in accordance with the signal modulation processing program so as to generate a data stream and stores the data stream in a modulated information storing unitas necessary. The modulation controllersends a data stream generated at that time or the data stream stored in the modulated information storing unitto a modulated signal outputting unit, and the data stream is outputted to a laser beam recorderby the modulated signal outputting unitat a predetermined clock. The present invention can be applied in cases of producing optical discs such as CD, MD, DVD and the like.
