A data edition method enabling reduction of the load of the edition processing of stream data recorded on a recording medium and realizing higher speed edition. It is assumed that the stream data recorded on the recording medium is managed as a file by a file system. The stream data is managed track by track using a track management data file managed by the file system. The edition of division and erase is executed track by track by rewriting the content of the track management information defining each track in the track management data file. With this configuration, it is not necessary to rewrite the file system when division or erase edition is executed track by track.
