摘要： A rewritable optical disk is disclosed which is compatible with a read-only optical disk in which a read-only area has tracks divided into a plurality of first sectors, signals being pre-recorded in at least one of these first sectors under a predetermined reproduction format. The rewritable optical disc comprises a read-only area located in an inner portion in which read-only tracks are formed, and a rewritable area located in an outer portion in which rewritable tracks are formed. Each of the rewritable tracks is divided into second sectors, and the signal is recordable in the second sectors under a predetermined recording format which includes the predetermined reproduction format as a part thereof and further includes another part specific to the predetermined recording format.
