Abstract

L'invention se rapporte aux dispositifs d'enregistrement-lecture d'une information sur une bande magnétique grâce à au moins une tête magnétique dont l'entrefer est en vis-à-vis de la bande, celle-ci étant animée d'un mouvement de défilement continu. Le dispositif selon l'invention utilise une bande du type << bande sans fin >> habituellement utilisée pour l'enregistrement du son. Il comprend n têtes magnétiques solidaires animées d'un mouvement de translation lent dans une direction transversale, chaque tête décrivant une piste continue, l'ensemble des pistes occupant toute la largeur de la bande et formant dans le sens de la largeur des tronçons de piste parallèles et équidistants. L'invention s'applique notamment à l'enregistrement de signaux vidéo utilisables dans un ensemble de reportage portatif.
