ABSTRACT:
A method and device for recording multiple information volumes on a record carrier, usually called multi-session recording, has a mapping unit (31) for opening a session by recording intro data including a first buffer zone at the beginning of the start zone of the volume, and a session control block (SDCB) in a remaining blank area of the start zone after the buffer zone. The session control block includes volume data indicative of the status and the contents of the session. The session is closed by recording session control data indicating that the information volume is closed in the remaining blank area, and closure data after the last user information recorded in the data zone for constituting the end zone of the volume. Further, the device has a detecting unit (32) for retrieving the session control block from said start zone.
