An apparatus of reproducing data recorded on a recording medium includes a pick-up unit, a local storage, and a decoder. The pick-up unit reads main data recorded on the recording medium. The local storage stores sub data associated with the main data. The decoder decodes the main data and the sub data using a PlayList file which includes a main path and a sub path, where the main path contains a PlayItem for play-back of the main data, and the sub path contains at least one SubPlayItem associated with the Playitem for play-back of the sub data in association with the play-back of the main data. The sub path may contain a single SubPlayItem or multiple SubPlayItems.
