Abstract

L'invention concerne l'enregistrement des signaux de télévision en couleur. Pour réduire la diaphonie au moment de la reproduction de signaux de chrominance enregistrés sur une bande magnétique sans bandes de garde entre pistes, on enregistre les signaux de couleur R-Y et B-Y sur les pistes successives N, N+1, ..., en respectant les règles suivantes : alignement des segments entre les pistes adjacentes; enregistrement du même signal dans les segments qui se trouvent côte à côte sur des pistes adjacentes; et rotation de la phase de la sous-porteuse dans une direction pour l'une des pistes, et dans la direction opposée pour la piste adjacente. Application aux magnétoscopes.
