Abstract: A data recording and reproducing apparatus supporting multi-path recording reproduction, and an information storage medium on which multi-path data is recorded. The information storage medium includes at least one clip that is a recording unit containing presentation data for respective paths, wherein presentation data in a selected path is continuously reproduced without changing paths, and additional path information regarding a block of the path is recorded separately from the presentation data. Accordingly, it is possible to more effectively use a recording space and reduce the frequency of jumping to clips, thereby effectively reading the multi-path presentation data from the information storage medium.
