A still video device in which identical image signals for one still image are recorded in two tracks of a recording medium, and the image signals recorded in the tracks are reproduced. The still video device has two magnetic heads for recording and reproducing the image signals. The image signals reproduced by the two magnetic heads are added together. An envelop-detected signal of the added-together image signals is obtained, and a phase of the reproduced signal is controlled in such a manner that the envelop-detected signal reaches a maximum value, whereby a C/N ratio of the reproduced signal is improved. Further, the recording mode of the image signals are determined based on the added-together image signals.
