1. An optical disk storing a data structure for managing reproduction, by a reproducing apparatus, of at least video data having multiple reproduction paths, comprising:
- at least one data directory storing more than one clip of video data for at least one segment of a title, each clip associated with a different one of the multiple reproduction paths of the segment; and
at least one data base directory, separated from the at least one data directory, storing a first management file and more than one second management files for managing reproduction of the video data by the reproducing apparatus, the first management file and the second management files being separate from the clips, the first management file including information indicating at least one playing interval in at least one of the clips for the reproducing apparatus to reproduce, and each second management file being associated with one of the clips and including management information for the associated one of the clips,wherein the first management file indicates reproduction paths of the multiple reproduction paths of the segment in one title, andwherein the second management files each include at least one entry point map identifying a presentation time and an address of the video data for the one of the clips associated with the second management file, and the at least one entry point map includes path change information related to changing reproduction paths.
