Abstract
The present invention relates to a method and apparatus for finalizing a dual layer disc medium. The present invention checks whether particular areas on each recording layer of a dual layer recording medium separated from each other, e.g., the innermost circumference of data zone and around an area of radius 4 cm, are unrecorded and records null data in a particular area found to be unrecorded and carries out finalization. The present invention has an advantage in that time needed for finalization is considerably reduced compared with a traditional procedure of recording null data throughout the entire unrecorded data section.
