ABSTRACT:
The present invention relates to an apparatus for copying the data content of a source multi-session DVD-storage medium to a destination multi-session DVD-storage medium, wherein the data content is organized in sessions and files, and each session contains a file allocation table storing at least the physical start address of each file within a session, and wherein the address space between two adjacent sessions on said DVD-storage media is different. The apparatus comprises a read unit for reading data from said first storage medium, a write unit for writing data on said second storage medium, and a controller unit for controlling said read unit and said write unit. An address converting unit adapted to analyze the file allocation table of each session and to apply a predetermined address offset to each address in the file allocation table before writing said data to the second storage medium is also provided. The invention also relates to a method for copying the data content of a source medium to a destination medium.
