<p><P>PROBLEM TO BE SOLVED: To provide a flexible system for recording positional data. <P>SOLUTION: A method and device for recording a plurality of information volumes on a recording carrier, usually called multi-session recording, is described. The device has a control means (20) for recording and retrieving positional data indicative of the position of the recorded information volumes. The control means includes a mapping unit (31) for generating a session map zone. In the session map zone, a session map block (SEM) containing position data of a closed session, namely, a completely recorded session is recorded. The device further has a detection unit (32) for retrieving the session map block from the session map zone. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
