An apparatus for recording and reproducing video data, audio data and graphics data representing sub-images such as subtitles to be superimposed with main images of the video data. Main data comprised of the video and audio data are compression encoded, multiplexed and recorded on a record medium such as a magnetic or optical disk. The graphics data are arranged in at least one file separate from the main data, and separately recorded on the recording medium. During reproduction, the graphics data file is read from the record medium at different times than the main data, and buffered separately. The arrangement and recording of the graphics data in a separate file simplifies editing and playback operations.
