Abstract
L'invention concerne un dispositif de commande asservie d'alignement Ce dispositif produit des impulsions de position d'une tête de lecture par rapport à un support d'enregistrement ainsi que des impulsions de commande de la vitesse du moteur d'entraînement de ce support, dont la phase est décalée progressivement de manière à obtenir un alignement précis de la tête par rapport aux pistes enregistrées. L'invention s'applique notamment aux enregistreurs d'images de télévision sur bande magnétique.
