Abstract
On fait appel aux techniques numériques pour l'enregistrement d'images sur des supports magnétiques constitués par des unités de disques d'ordinateurs usuelles. Il est notamment prévu pour l'élimination des décalages temporels qui peuvent survenir en cours d'enregistrement ou de reproduction un correcteur de base de temps avec un registre à entrées multiples rythmé par un signal d'horloge asservi aux données et par un signal d'horloge stable de référence, les données étant restituées ainsi à une fréquence fixe à la sortie. Application à l'enregistrement et à la reproduction d'images fixes, ainsi que de séquences d'images animées.
