Abstract

Abstract According to the present invention, there is provided a method for manufacturing a ROM type optical disk in which application program data are written, wherein application program data ([2], [3]) having no information on positions for writing data stored in a storage device (1) are written in an optical disk (3) for supplying data by a data writing optical disk drive (2), and then, the application program data ([2], [3]) and information ([1]) on positions for writing data are read out of an optical disk (3) for supplying data by a data reading optical disk drive (4) and stored in a storage device (5) for manufacturing a ROM type optical disk.
