Abstract
PURPOSE: To eliminate the fraction of the pulse number necessary for the 1-track feed and thus to enhance the action accuracy by driving the capstan motor via the one-to-even number output of the counter which uses the pulse frequency at the normal recording time as one-to-odd numbers.
CONSTITUTION: When the tape feed speed is set to 1/7 the normal recording time, video signal (2) obtained by sampling the continuous field video signal (1) to 1/7 is displayed. The stepping motor shifts the 1-track equivalent distance by pulses P1∼P6 and stops for the section equivalent to the 7th pulse. During this period, the sampling video signal is applied to the ratory head to be then recorded on one track. In other words, the diameters of the capstan, the stepping motor pulley and others are decided so that one track is fed with 6 pulses. As a result, no fraction is caused to the feed pulse per track in any sampling mode, so the shift distance becomes constant per track to secure the tape feed action of a high reproduction accuracy.
