<p>PURPOSE:To perform satisfactorily a joint shooting, by controlling the rotary phase of a capstan motor with a tracking error signal obtained from a reproduced pilot signal in a short period when a pause mode is changed to a record mode, then executing normal control. CONSTITUTION:A magnetic tape 27 is shifted toward an arrow 28 by a capstan 43. A rotary disk 29, a rotary magnetic head 30 and a frequency generator FG32 are connected directly to a cylinder motor 31. A head 35 detects the pulse signal of the disk 29 and supplies it to a cylinder motor 31. In a recording mode, a phase comparator 51 compares the vertical synchronous signal supplied to a terminal 38 with a frequency dividing signal given from a capstan FG45, and both signals are supplied to a speed control circuit 47. In a reproduction mode the output of a pilot signal processing circuit 57 is supplied to the circuit 47. When the record mode is switched to a pause mode, a tape 27 is rewound for a short time. Then the phase is controlled with the output of the circuit 57 for a short time, and the normal control is executed after the phase is stabilized.</p> |
