Abstract
A recording/playback apparatus records data and contents management information of the data on a randomly accessible recording medium, or plays back the data and contents management information from the recording medium. Upon changing the contents of group management information required to group arbitrary data independently of a file system, and management information, the contents of a playlist indicating a playback sequence of the data are changed. Upon creating a playlist, group management information corresponding to that playlist is automatically created, and a data list to be referred to by the playlist is updated.
