Abstract
An optical disk has two sides for recording data and at least one recording area for each side. Each recording area is associated with an attribute which designates whether the corresponding recording area is an area which permits rewriting or an area which does not permit rewriting. Data representing the attribute for the at least one recording area of each side is recorded in a structure management table provided in a predetermined part of the disk of each side. The two sides of the disk have different attributes.
