Abstract
L'invention concerne un appareil d'enregistrement et de reproduction de signaux d'image de télévision sur bande magnétique mobile à des vitesses différentes. Quand la vitesse de la bande est réduite, en éliminant les bandes de garde entre les pistes et en réduisant les largeurs de ces dernières pour obtenir une plus grande densité d'enregistrement, l'excursion de fréquence des signaux modulés en fréquence appliqués aux têtes magnétiques est réduite pendant l'enregistrement dans le but de réduire au minimum les signaux parasites dus à la transmodulation. L'invention s'applique notamment à l'enregistrement sur bande magnétique des signaux de télévision en couleurs.
