Abstract

L'invention concerne l'enregistrement magnétique de signaux vidéo. L'invention s'applique à l'enregistrement de signaux, comme les signaux SECAM, dans lesquels un paramètre des composantes de chrominance varie périodiquement Les pistes adjacentes, comme les pistes 3A1 -3B1 , 3A2 -3B 2 , etc, sont disposées de façon à aligner les parties des composantes de chrominance qui présentent les mêmes caractéristiques par rapport au paramètre considéré, ce qui permet de supprimer la bande de garde entre ces pistes, pour augmenter la densité d'enregistrement. Application à l'enregistrement magnétique de signaux PAL ou SECAM.The invention relates to the magnetic recording of video signals. The invention applies to the recording of signals, such as SECAM signals, in which a parameter of the chrominance components varies periodically. Adjacent tracks, such as tracks 3A1 -3B1, 3A2 -3B 2, etc., are arranged in such a way in aligning the parts of the chrominance components which have the same characteristics with respect to the parameter considered, which makes it possible to eliminate the guard band between these tracks, in order to increase the recording density. Application to the magnetic recording of PAL or SECAM signals.
