1. A machine readable medium having a data structure for managing reproduction of a data stream recorded on the machine readable medium by a reproducing apparatus, comprising:
- a navigation area storing a navigation map for managing reproduction of the data stream by the reproducing apparatus, the navigation map including a plurality of mapping entries, the navigation map including a field for representing a number of mapping entries in the navigation map, the navigation map mapping presentation time with location information for a corresponding segment of the data stream stored on the machine readable medium for each of the mapping entries, and the navigation map including, for each of the mapping entries, at least a first field for representing the location information of the corresponding segment of the data stream, and a second field for representing multi-path related information of the corresponding segment of the data stream, the first and second fields being separate fields.

Abstract
The recording medium includes a data structure having a navigation map. The navigation map includes a number of map entries and indicates the number of map entries. Each map entry maps presentation time with location information for a segment of the data stream stored on the recording medium. The navigation map also includes multi-path information when the data stream includes segments representing multiple reproduction paths.
