Each of salvage markers contains a recognition pattern for recognizing a salvage marker, and identification information for identifying files to which audio data “Audio”, and video data “Video” belong. If the recording process fails to end in a normal state, the salvage markers are detected from the recognition pattern contained in the salvage markers, and the file having the audio data and the video data belonging thereto is identified by the file identification information. The present invention is applicable to a video processing apparatus. ## Claims ### Claim 1 A recording apparatus for recording data managed as files onto a recording medium, comprising: generator
