Summary:A method is described for writing an optical disc (2) having a user storage space (USS). The method comprising the steps of dividing the storage space of an optical disc (2) into, on the one hand, one or more sections (80; 181, 182, 183, 184) where an application is allowed to write and, on the other hand, one or more sections where it is not allowed to do so. The location and extent of the allowed section(s) is either fixed in format or determined by one or more parameters (BA, L, VAPT) stored on disc. A signal processing system (120) of a video recorder apparatus (100) is designed, before attempting a write operation to a disc (2), to determine the allowed storage area (VASS) for the present disc, and to select free area (72) for writing only within the allowed storage area.
