Abstract
PURPOSE: To bring a tape under drum servo-control on the basis of the vertical synchronizing signal of an external signal when the external signal is recorded, by editing the tape while synchronizing a signal reproduced from the tape with the external signal.
CONSTITUTION: Vertical synchronizing signal V of a video signal inputted in recording mode and pulses PG obtained according to the rotational phase of head drum 7 are phase-compared 15 to obtain an error voltage. The VTR like this reproduces signals from tape 1 with the 1st video signal A recorded and also inputs the 2nd video signal B and when the reproduction of tape continued to a fixed position and signal B is recorded connecting to signal A, the tape is brought under drum servo-control on the basis of vertical synchronizing signal Vb of signal B in reproduction mode. At this time, synchronizing signal Vb and vertical synchronizing signal Va of signal A are phase-compared and according to the phase difference, pulses are delayed.
