Abstract
The present invention provides a finalization method and apparatus which enables out a reproduction of an optical disk such as a DVD-RAM by using a reproduction apparatus which carries out CLV reproduction. The finalization method according to the present invention includes creating an unrecorded area map of an optical disk on the Logical block address (LBA). In order to execute in the host application a conversion from LBA to Physical Block Address (PBA) which is normally executed in an optical disk drive, a conversion table from LBA to PBA is created. According to this conversion table, the unrecorded area map is converted from LBA into PBA so as to assure the area to be finalized. A dummy data is recorded in the aforementioned assured area of the optical disk.
