Claims

[Scope of utility model registration request]

A magnetic recording/reproducing device that alternately records left and right channel audio signals frequency-modulated using different carrier frequencies on a magnetic tape via a pair of magnetic heads, and the pair of magnetic heads is used to record audio signals of left and right channels frequency-modulated using different carrier frequencies on a magnetic tape. A head switching control means for switching so that the end portion of one head and the beginning portion of the other head are partially overlapped, and a demodulated output of a high frequency near the upper limit of the audible band among the reproduction outputs of the pair of magnetic heads. A magnetic recording and reproducing device comprising a high frequency mixing circuit that mutually mixes left and right channels of reproduced audio.
