Abstract
An audio signal recording and reproducing system in an apparatus for recording and reproducing a video signal with respect to a recording medium by one or a plurality of rotary heads, comprises a first delay circuit for delaying an input recording audio signal by a predetermined time interval, a multiplexing circuit for multiplexing a non-delayed signal which is the input recording audio signal and an output delayed audio signal of the first delay circuit, to obtain a multiplexed audio signal for recording, a recording and reproducing circuit for multiplexing the video signal and the multiplexed audio signal for recording thus obtained, to perform recording and reproduction of the multiplexed signal with respect to the recording medium by the one or a plurality of rotary heads, a reproduced video signal obtaining circuit for separating the video signal from a signal reproduced by the recording and reproducing circuit, to obtain a reproduced video signal, a separating circuit for separating the non-delayed audio signal and the delayed audio signal of the multiplexed audio signal from the signal reproduced by the recording and reproducing circuit, a second delay circuit for delaying the separated non-delayed audio signal by a delay time equal to the delay time of the first delay circuit, and a switching circuit for alternately switching the separated delayed audio signal and an output delayed audio signal of the second delay circuit, to produce a continuous reproduced audio signal.
