ABSTRACT:
A molding and film forming apparatus700molds a disc substrate from a stamper330formed from an optical disc disc-master320and forms a coating film, for example, a reflective film onto the disc substrate, thereby forming a recorded optical disc360. A postscript apparatus200writes postscript information once onto an optical disc340formed by the molding and film forming apparatus700. As postscript information, a laser beam is irradiated to a predetermined interval of the optical disc340, a portion which is detected as a pit is formed, and an optical disc350on which postscript information420has been recorded is formed. Identification information which enables each optical disc340to be identified can be postscribed. The postscript information is recorded in a conventional format and the postscript information can be reproduced by an existing reproducing apparatus.
