Abstract

1,136,813. Video recording and playback. AKAI ELECTRIC CO. Ltd. 11 Jan., 1966 [5 Nov., 1965], No. 1141/66. Heading G5R. A video signal is recorded on tape T by a recording head 113 and reproduced by a pair of heads 117, 119, the first of which has a short gap for reproducing the high frequency portion of the signal and the second a larger gap for reproducing the low frequency part of the signal. The output signals from the heads are amplified 118, 120 and applied via a mixer 121 and equalizer 122 to an output terminal 124. The playback heads are spaced a distance corresponding at a selected tape speed to the time interval of a picture field multiplied by n, where n is an integer from 1-4.
