In a recording and reproduction method for recording compressed digital data on magnetic tape by a helical scanning method or for reproducing compressed digital data recorded on magnetic tape by the helical scanning method, a first recording area, including an audio sector, and a second recording area, including a track-synchronization-information sector, a video sector or a video-and-audio-mixed sector in which audio data and video data are mixed, a sub-code sector, and a search-data sector in which data used in variable-speed reproduction is recorded, are sequentially disposed in the direction from the top to the end of each track on the magnetic tape with an interference area disposed therebetween. Data is continuously recorded in each sector in the first recording area and the second recording area. In the second recording area, the sub-code sector or the search-data sector is disposed after the video sector or the video-and-audio-mixed sector.
