1. A recording medium having a data structure for managing reproduction of at least video data representing multiple reproduction paths, comprising:
- a data area storing at least video data as a transport stream in more than one stream file, each stream file associated with a different one of the multiple reproduction paths, and the stream files being interleaved with one another; and
a navigation area storing at least one navigation list file, the at least one navigation list file including at least a first navigation data item and a second navigation data item, the first navigation data item referencing more than one map for managing the multiple reproduction paths, a flag being stored in the first navigation data item, the value of the flag indicating that the first navigation data item references more than one map, the first navigation data item including an indicator having a value of the number of reproduction paths associated with the first navigation data item, the second data item referencing a single map for managing a single reproduction path, a flag being stored in the second navigation data item, the value of the flag indicating that the second navigation data item references a single map, each navigation data item including an identifier identifying at least one map file associated with the navigation data item, the map file including at least one map referenced by the navigation data item providing position information for the video data, the navigation list file being separate from the map file and stream files.
