ABSTRACT:
A method of recording video data and the accompanied sound data capable of editing the video data and sound data track by track without editing gaps is disclosed. The track format includes a first block of tracks for video data and a second block of tracks for sound data for a predetermined number of frames. Another method of selectively recording one of a plurality of kinds of video data having different amounts of data per frame or field and the accompanied sound data (NTSC and PAL for example) is provided. In this method, the video data and sound data are recorded with a recording and editing unit which is a determined by a common multiple of the selected one of kinds of video data among the amounts of data of the different kinds of video data. In NTSC method the video and sound data are receded every six frames or fields and in the PAL method, the video and sound data are recorded every 5 frames or fields, so that a track pattern having T=24 tracks including P tracks for sound data and T-P tracks for video data are recurrently recorded. The video and sound data are recorded track by track, so that video and sound data can be edited tack by track.
