ABSTRACT:
Excessive cross talk between adjacent tracks can occur in a video recorder in which the line-synchronization pulses of adjacent tracks are not adjacent, in long-play or 8-mm video for example. The BAS signal is in accordance with the invention pole-reversed from track to track during recording when the video carrier is frequency-modulated in such a way that the level of the synchronization pulse corresponds alternately to the low and to the high frequency of the video carrier.
