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 unit130has a modulation processing program required for producing an optical disc master320stored therein in advance. Information data recorded in an master optical disc310is reproduced by an information reproducing unit110and is outputted to a modulation controller120. The modulation controller120carries 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 unit140as necessary. The modulation controller120sends a data stream generated at that time or the data stream stored in the modulated information storing unit140to a modulated signal outputting unit150, and the data stream is outputted to a laser beam recorder200by the modulated signal outputting unit150at a predetermined clock. The present invention can be applied in cases of producing optical discs such as CD, MD, DVD and the like.
