Abstract

Enregistreur à disque magnétique comportant un mécanisme perfectionné de commande du déplacement d'un transducteur. Ce mécanisme comprend un élément de guidage qui est orienté transversalement à l'axe de rotation du disque 12 et qui présente une surface de guidage. Le transducteur est monté sur un chariot parcourant ladite surface de guidage. L'élément de guidage presente une fente dont la largeur peut être réglée à l'aide d'une vis afin de modifier le profil de la surface de guidage et d'incliner ainsi le chariot portant le transducteur lorsqu'il est déplacé vers la périphérie du disque. La tête transductrice reste ainsi dans une orientation, par rapport au disque, permettant un enregistrement optimal. Domaine d'application : enregistreurs à disques souples.
