Abstract
PURPOSE: To detect a desired video recording position, by recording the mark signal in the corresponding position at a certain distance from the desired video recording position and by culculating back the said corresponding distance from the mark signal detection position.
CONSTITUTION: Mark signal 8 is recorded in the corresponding position at a certain distance from a desired video recording position on video tape 5. Next, tape 5 is set between tape guides B and B' of detecting part 4 of picture recording position, and motor (g) of control signal retrieving part G and circuit (l) are operated. Then, the knob X of slow speed feeding device E is turned, and the tape is fed forward and backward to detect mark signal 8, and the sound is changed from the low sound to the high sound, and turning is stopped in the position of cutoff. At this time, line Q connecting indexes C and D becomes recording video track 7 of the desired picture. Thus, the position where the desired video is recorded on the video tape is detected accurately.
