摘要： In a helical scan apparatus having a rotary head or heads for recording and/or reproducing video and audio signals in oblique tracks on a magnetic tape with the recorded audio signals being recorded in overscan areas of the oblique tracks and with the pitch of the tracks being different as a result of changes in the tape speed for different recording modes; index signals are recorded by the rotary head or heads at predetermined positions in the overscan areas of a plurality of the oblique tracks for a period of time dependent upon the recording mode previously used for recording the video and audio signals. Therefore, in a program search operation employing high speed playback, the index signals can be extracted from the output of the rotary head or heads for identifying a respective program or event irrespective of the recording mode with which the video and audio signals were recorded.
