<p>A recording medium which stores additional information for restoring digital data streams, and a recording method and a restoration method therefor. The restoration method includes determining the scope of unification of data streams which were divided by editing/re-recording and are to be restored, after checking whether or not the divided data streams can be unified with other data streams, according to additional information which indicates that a divided data stream was combined with another data stream before division; and updating additional information on a plurality of data streams in the determined unification scope so that the additional information corresponds to one data stream which corresponds to the determined unification scope. Accordingly, divided data streams can be restored to an original state which existed before editing/re-recording.</p> |
