Video signal is again administration device with in addition to again administration barrier against signals from the difference between the recording - and reproduction speed

PURPOSE:To make it possible to reproduce a good-S/N and small-skew still, a slow picture of an arbitrary speed and a double speed picture of an arbitrary speed by a simple constitution in a VTR. CONSTITUTION:Bimorph plate 61 is fitted obliquely to head fittting substrate 62 on a rotary head drum, and heads Ha and Hb are fitted to bimorph plate 61, which is fitted obliquely, in parallel to substrate 62 through spacer 63. Then, displacement direction Q of this bimorph 61 is so controlled that the displacement of slippage components (3/4H) of horizontal synchronizing signals in the running direction of the head can be obtained simultaneously when the displacement of one-pitch (the interval of tracks) components in direction p orthogonal to running direction b of the head is performed. At a still reproducing time, saw tooth wave A is applied to bimorph plate 61a of head Ha in odd fields, and saw tooth wave B is applied to bimorph plate 61b of head Hb.
