Abstract
Transducteur de reproduction à commande de pistage pour dispositifs destinés à reproduire des signaux enregistrés sur des milieux d'enregistrement tournant. Le transducteur 16 comprend un organe de reproduction 20 pour suivre une piste d'un milieu d'enregistrement Il, un organe en porte-à-faux 21 monté sur une console 24 par une patte 23 et un amortisseur 22 et dont l'extrémité libre porte l'organe suiveur 20, des organes pour détecter toute déviation de l'organe 20 depuis sa position correcte sur la piste et pour délivrer alors un signal de commande de pistage, des filaments 28 pour amener le courant de ce signal à l'organe en porte-à-faux et au moins un aimant 30 créant un champ magnétique pour déplacer l'organe 20 afin de le ramener dans sa position correcte. Application à l'obtention d'une commande de pistage plus précise lors de la reproduction de signaux enregistrés, notamment sur des milieux d'enregistrement tournants.
