A sync crosstalk cancelling circuit features a record/playback head, capable of sync recording, molded in one piece with a record head section and playback head section and another record/playback head identically constructed. The recording head section of the record/playback heads are either connected in series or parallel at the same polarity, with the same recording current applied to both recording head sections, and at the same time, playback signals reverse in polarity to each other are obtained from the playback head sections of the record/playback heads, their gains adjusted and then applied to a mixing circuit. The mixing circuit outputs the playback signal with the crosstalk elements cancelled.
