An optical disc apparatus includes an optical head configured to irradiate a light beam to an optical disc medium to record and reproduce data, wherein the optical disc medium has a record track which is divided into an inner circumferential control data recording area, a user data recording area and an outer circumferential control data recording area from an inner circumferential side; and a control unit configured to control a position of the optical head and to supply data to be recorded to the optical head. After a user data is recorded in the user data recording area, an ending process state data which shows a progress state of an ending process for recording a control data in a predetermined area of the user data recording area is recorded in a predetermined area of the inner circumferential control data recording area.
