ABSTRACT:
A method of recording and reproducing audio signals and corresponding visual signals in parallel tracks extending in the longitudinal direction on a magnetic tape, includes the steps of recording the audio signals in first and second primary tracks on opposite sides of the tape in the widthwise direction thereof; and alternately recording a first visual information signal corresponding to the audio signal in the first primary tracks and a second visual information signal corresponding to the audio signal in the second primary tracks in a single secondary track positioned in the center of the tape in the widthwise direction thereof, the first visual information signal being recorded in first information blocks in the secondary track and the second visual information signal being recorded in second information blocks in the secondary track in an alternating relation with the first information blocks such that only the first visual information signal is reproduced when reproducing the audio signal from the first primary tracks and only the second visual information signal is reproduced when reproducing the audio signal from the second primary tracks. The preset invention is also directed to apparatus for performing the above method.
