PROBLEM TO BE SOLVED: To provide an optical disk recorder or the like that can easily realize after-recording. SOLUTION: The optical disk recorder that records received video and audio signals to an optical disk, is provided with a means that encodes the video signal to generate a video stream 72, a means that encodes the audio signal to generate a 1st audio stream 73 and generates a 2nd audio stream 74 for after-recording on the basis of the generated 1st audio stream 73, a means that multiplexes the generated video stream 72 with the 1st and 2nd audio streams 73, 74 to generate a video object 70, and a means that records the generated video object 70 onto the optical disk.
