Abstract

a. Dispositif de positionnement de têtes magnétiques pour mécanismes à disque souple (disque Floppy). b. Il est prévu, comme élément d'entraînement pour la tête d'inscription, un cône à spirale comportant deux moitiés identiques alignées axialement, dans les flancs des spirales desquelles s engagent des épaulements reliés à la tête d'inscription. Pour la compensation de l'erreur angulaire de pas du moteur pas à pas, des surfaces de repos sans inclinaison sont prévues sur les flancs des spirales. c. L'invention trouve son application principale dans les mécanismes à disque souple (disque Floppy).
