ROTARY HEAD TYPE MAGNETIC VIDEO RECORDING AND REPRODUCING DEVICE

摘要

PURPOSE:To attain the consecutive recording with no noise on the screen of a TV receiver when the corresponding section is reproduced, by using a circuit which secures the synchronization of the timing of the recording part indicating signal of a VTR with the head switching signal. CONSTITUTION:A recording mode setting signal (c) of the Q output is set at a high level at the starting rise edge of a head switching signal (b) after a start indicating signal (a) is changed to a high level from a low level. Thus the video recording starts. This recording ends when the signal (c) is set at a low level at the starting rise of the signal (b) after the signal (a) is changed to a high level from a low level. In such a way, the starting point of a recording mode is always set at a place near the vertical synchronizing signal of the 1st video signal recorded previously. Thus the noises if produced at a switching point are not given on a reproduced screen.
