A magnetic recording and reproducing system comprises a separating circuit for separating samples constituting a digital audio signal into odd and even numbered samples within each field of an input video signal by assigning sequential numbers to the samples which are sequentially obtained by the sampling, a first circuit for delaying the odd (or even) numbered samples by a predetermined time, an encoder for encoding delayed odd (or even) samples and undelayed even (or odd) samples obtained from the separating circuit for every one field and for producing an encoded digital audio signal, a decoder for decoding the encoded digital audio signal reproduced from a magnetic tape and for producing the delayed samples and the undelayed samples, a second circuit for delaying the undelayed samples from the decoder by the predetermined time, and a circuit for producing a reproduced digital audio signal from the delayed samples obtained from the decoder and delayed samples obtained from the second circuit and for producing a reproduced analog audio signal by subjecting the reproduced digital audio signal to a digital-to-analog conversion, so that a click noise is minimized at a joint of two successive recordings.
