PURPOSE:To suppress fluctuation in screen without changing tape format and the structure of video heads by providing a field memory storing a video signal at least for one field's share, storing one head output to a storage means and outputting the stored data in place of the other head output at still or slow reproduction mode. CONSTITUTION:When the rotary heads rotate around once, signals for two fields' share, i.e., A and B are outputted from the heads A and B, and the A head output is outputted at it is to a TV receiver in this case and also this A head output is written in a field memory. When the B head output is going to be outputted at the next 1 field, the A head output written before is outputted to the TV receiver. The synthesized output is as A A A A A A and the outputs of an even number order are the stored data being outputs before one preceding data. Thus, the B head output being a cause to fluctuation is cut, and even if the recording picture is a dynamic picture with fast movement, a picture without fluctuation is obtained. Further, in storing the B head outputs to the storage means, the synthesized output is as B B -B, and the picture without fluctuation is obtained similarly. |
