Abstract

PURPOSE:To execute the continuity of a CTL signal at a consecutive recording part without fail by detecting the moving quantity of the tape of a part to execute the consecutive recording with the numeric value counted from both CTL signal and capstan FG signal. CONSTITUTION:By a CTL signal outputted at the time TE when a picture recording action is completed, a counter 21 is rest, folded back from a stoppage point T0 of a tape to overrun to a certain extent from an end point and the tape for the consecutive recording is re-wound. Then, an FG pulse from an FG 19 of the capstan is counted by the counter 21, at the time TS, which becomes a prescribed value, the tape is made into the waiting condition. When a recording is obtained from this, the tape is moved in the forward direction with a reproducing mode and counted by a counter 22. The CTL signal of a zero resetting circuit 16 is detected, and made into the resetting signal. Simultaneously, the FG clock is inputted to a counter 26 and the output is reset by the fall of the 1/2 of a synchronizing signal VD of an external input. A capstan motor 12A is controlled so that the counting output of counters 22 and 26 can be made incident and the consecutive recording is executed.
