Claim:
Method of contiguously recording a sequence of ordered audio and video information signals, such as video/audio information, and corresponding management information signals, such as video management, menu information or file information, on a disc-like recording medium of the write-once type, such as an optically recordable and readable disc, the recorded information complying to the requirements of ordering of such information as defined by a disc of the read-only type or of the rewritable type; the method comprising the following steps: allocating a reserved area within a linear addressing space; contiguously recording the audio and video information signals in a video recording area located succeeding the reserved area; recording corresponding first management data in a temporary overview space succeeding the video recording area; generating a mapping table for mapping the recorded first management data to address locations in the reserved area; recording the mapping table in the temporary overview space; wherein the step of generating the mapping table comprises selecting and performing one of the following alternative steps, if a respective one of the following conditions applies: generating the mapping table in the form of a first mapping-table structure, if audio and video information signals representing an encrypted information content are recorded or if the recording medium already contains encrypted information content due to prior encrypted recording, and generating the mapping table in the form of a second mapping-table structure differing from the first mapping-table structure, if audio and video information signals representing a non-encrypted information content are recorded and if the recording medium does not contain any prior encrypted information content.
