Abstract

L'invention concerne une tête de transducteur magnétique. Cette tête comporte un noyau magnétique avec un entrefer et un enroulement de quelques spires passant dans la boucle du noyau et dont une spire passe dans l'entrefer en affleurant sa surface extérieure. L'invention s'applique notamment à une tête d'écriture et de lecture sur une mémoire à disque.
