    摘要： Video and audio data are recorded onto video and audio signal recording areas of a track of a record medium, these areas being included either in one of several segments in the track or the track being comprised of only a single segment of video and audio signal recording areas. Audio data that is supplied at substantially the same time as the video data is compressed and recorded in a first audio sector of the audio signal recording area. Then, depending upon whether a first or second audio signal recording mode is selected, either compressed audio data which is derived from the audio data supplied at substantially the same time as the video data or independent compressed audio data is provided. The derived or independent compressed audio data is recorded in a second audio sector of the audio signal recording area.

    摘要： Rotary head recording and/or reproducing apparatus in which respective oblique tracks on a record medium are scanned, each track having an information signal area in which information data is recorded and a track following area in which a tracking control pilot signal is recorded. The track following area precedes the information signal area; and in the preferred embodiment, an additional track following area follows the information signal area. The pilot signal is recorded in only a portion of the track following area, the remainder of which has timing sync data recorded therein. In an after-recording mode the timing sync data is reproduced, detected and used as a reference to define an after-record area.
