Abstract
Abstract In a writable optical disc such as a CD-WO and CD-MO having a program area where, by using a recording format capable of recording data in the form of a main code and a subcode, program information is recorded in the form of the main code and control information thereof is recorded in the form of the subcode and also a lead area formed adjacent to the program area where information constituting a table of contents (TOC) only which is extracted from the control information is recorded in the form of the subcode, data for mastering the information recorded on the optical disc is recorded in the form of the main code in at least a part of the lead area.
