Abstract
A recording apparatus includes a detector for detecting a video attribute, a detector for detecting an audio attribute, and an address information generator for generating specific address information which indicates a data write address at the time when the video attribute of the audio attribute changes, on the basis of the outputs from the detectors. The specific address information is written in a recording area of an optical disk, which area corresponds to VMGI constituting management information (VMG information) for each VOB. Therefore, when playing an audio video stream recorded on the optical disk, quick access can be made to the recording position in the stream where the attribute change occurs.
