Abstract

Dispositif d'entraînement d'une tête de lecture d'un disque souple de mémorisation de données. Le dispositif d'entraînement comporte un moteur linéaire pas-à-pas 26 pourvu d'un stator 30 comportant plusieurs positions polaires auxquelles sont associés des enroulements qui sont excités dans différentes phases ainsi qu'un curseur 28, ce dernier comportant plusieurs dents 34 qui coopèrent avec les dents du stator dans les différentes positions polaires afin de former un trajet de réluctance variable dans le curseur, des rainures longitudinales du curseur coopérant avec des rainures semblables du stator de manière à recevoir des organes d'appui servant à supporter le curseur dans l'entrefer de stator. Application aux systèmes de mémorisation à disques souples.
