Provided is a recording apparatus that prompts a user to judge whether non-referenced part in a DVD should be deleted or not, thereby facilitating cleanup of recorded contents in the DVD. A playlist editing unit (15) obtains a PL by performing a playlist editing, where the playlist is a logical playback path defined on a VOB recorded in the DVD and contains at least one playback section defined by the user. After the playlist editing is performed, a non-referenced part extraction unit (17) displays to the user a plurality of remaining parts resulting after subtracting from the entire VOB the playback section specified by PL information, as a plurality of non-referenced parts in a moving image stream. A substantial editing unit (18) deletes any of the displayed non-referenced parts, according to a user operation.
