Abstract
PURPOSE: To compensate signal drop-out at a reproducing time to reproduce stably joints of recorded pictures, by synchronizing rotation of a capstan and video signals with each other.
CONSTITUTION: Capstan motor 17 is rotated 60 times per 1 second phase-synchronusly with video signals by action of the phase synchronizing loop which is constituted by photo detector 21, shaping circuit 22, and motor control circuit 23, and at this time, switch circuit 33 is turned on to record signal D corresponding to the output of FF24 simulraneously with recording video signal C onto tape 11. The period of signal D is the double of the vertical period of output signal B of a TV camera, and rise and fall of signal D are synchronized with the vertical synchronizing signal of signal B. Since signal D is recorded continuously constantly by synchronizing head 16 even if the capstan motor is decelerated or stopped, the vertical synchronizing signal is not broken even at joints of recording for the output of switch circuit 36 at a reproducing time, and consequently, step-out in TV receiver 10 can be prevented.
