Abstract
An optical disc medium includes a system area and a data area following the system area. A plurality of sets of an extended record control data area, a bordered area, and a border are possibly set in the data area continuously from the system area, and a first set of the plurality of sets does not include the extended record control data area. A user data is recorded in each of the bordered areas. In each of the plurality of sets other than the first set, a record control data associated with the user data which is recorded in the bordered area of the set is recorded in the extended record control data area.
