Patent ID: 7865059

Claim:
Device for recording information, the information including real-time data within a real-time data stream in accordance with a predefined recording format, which device comprises recording means for recording optically detectable marks in a track on a record carrier representing the information in information blocks having logical addresses, and control means for controlling the recording by locating each information block at a separate physical address in the track, the control means comprising: allocation means for generating and maintaining the allocation information, the allocation information including at least one logically contiguous range of blocks allocated to at least a part of the real-time data stream, addressing means for translating the logical addresses into the physical addresses and translating the physical addresses into logical addresses in dependence on allocation information, auxiliary data means for processing auxiliary data related to the real-time data and for recording the auxiliary data as auxiliary blocks on the record carrier, the auxiliary data means being coupled to the allocation means, whereby the allocation means assigns a physical addresses to the auxiliary information blocks, which physical addresses of the auxiliary blocks are excluded from allocation to logical addresses and are within a physical address range, which physical address range is allocated to the said part of the real-time data stream corresponding to the at least one logically contiguous range of information blocks.
