Abstract

Système de maintien sur piste automatique d'une tête transductrice permettant un ralenti continu. Il utilise un positionnement transversal de la tête transductrice pour faire suivre à celle-ci de façon précise une piste au cours de la reproduction et, à la fin de la piste, pour amener en position voulue, soit pour reproduire la piste suivante immédiatement adjacente, soit pour reproduire la même piste que précédemment, ou encore pour reproduire une autre piste, de manière à obtenir l'effet de mouvement spécial approprié. Il convient notamment aux appareils de reproduction et d'enregistrement à balayage hélicoïdal.
