Abstract

a. Dispositif de correction d'erreur de poursuite de trace d'un appareil de reproduction vidéo. b. Dispositif caractérisé en ce qu'il comporte un moyen pour modifier l'amplitude du signal en dents de scie dans une direction et un moyen pour comparer le niveau du signal reproduit par le transducteur suivant une chronologie prédéterminée pour chacune des sections unitaires et l'amplitude du signal en dents de scie continue de changer dans cette direction aussi longtemps que la sortie du moyen de comparaison se trouve dans un état, l'amplitude du signal en dents de scie s'arrêtant de changer dans une direction lorsque la sortie du comparateur passe dans un autre état de façon à maintenir pratiquement l'alignement entre le transducteur de signaux et la section de piste, en mode de reproduction, lorsque la vitesse relative entre le transducteur de signaux et le support d'enregistrement est différente de celle du mode d'enregistrement.
