Abstract

Dispositif de réglage de la vitesse et de la position en rotation d'un disque d'enregistrement par rapport à des têtes de lecture et d'écriture. Il comporte une roue 20 dont le bord présente des encoches 22 et qui est fixée qur un arbre 12, sur lequel un disque 10 est également fixé, de manière qu'un moteur 14 fasse tourner la roue et le disque ensemble. Un transducteur 16 produit des impulsions en réponse au passage des encoches équidistantes 22, et ces impulsions sont utilisées pour régler la vitesse du disque. Deux des encoches de la roue 20 sont séparées l'une de l'autre par un intervalle qui diffère de celui séparant les autres encoches, afin que le passage de ces deux encoches devant le transducteur 16 provoque l'apparition d'une impulsion d'in dexage qui correspond à un point de référence sur le disque. Application à l'enregistrement et à la reproduction sur dis ques magnétiques.
