摘要： PURPOSE: To attain a joint shooting with a portable VTR by recording a time code on a control track in a record mode, rewinding a tape when the time code recording is discontinued and keeping the rewound amount of the tape according to the number of pulses detected out of a time control signal.
CONSTITUTION: In the record mode a time code signal is supplied to a control track head 20 from a time code generator 17 via a signal selection switch S19. At the same time, both video and sound record signals 31 and 32 are also recorded. When the record mode is over, the tape drive is stopped by a switch 28. Then the revolving direction of a capstan motor 8 is reversed by a revolving direction switch circuit 7. The switch S19 is changed to the reproduction side, and the time code signal reproduced by the head 20 is supplied to a synchronizing word detector 15. The detection pulses are counted by a counter 14 and supplied to the switch S28. Thus the rewound amount of the tape is kept at a fixed level and the recording is restarted with the timing where a counter 13 counts the input reference frame pulses 33. Thus the joint shooting is possible with a short cut.
