Abstract

PURPOSE: To perform edit with high accuracy and reliability by a simple unit, by reproducing the stop position signal recorded on magnetic tape and the address signal near the signal and retrieving the lead-in.
CONSTITUTION: At fast feed or rewinding, the running distance substraction section 27 subtracts the actual running distance from the running distance to the objective address set to the running distance operation section 25 via the preset switch 26, according to the tape timer pulses ϕ1, ϕ2 from VTR. Further, with the output of the operation section 25 before a given time of tape to reach the objective address, the control section 28 controls the tape speed and converts the mode into the reproduction mode. Thus, the address signal immediately before or after the stop position signal of tape, is demodulated at the address code demodulation circuit 22, and via the address coincidence detection circuit 24 starting the operation with the coincidence with the preset address, required lead-in is retrieved according to the stop permission signal produced at the detection of stop position, and with a simple constitution without requiring specific time code, the edit with high reliability and accuracy can be made.
