Abstract

L'invention concerne un dispositif d'enregistrement ou de lecture d'informations sur la surface d'un disque magnétique flexible. Il comporte une surface fixe de forme cylindrique et un dispositif de mise en rotation du disque qui, lorsqu'il tourne, épouse la forme de la surface cylindrique dont il reste séparé par un coussin d'air. Le disque comporte une ou plusieurs ouvertures destinées à recevoir des broches de positionnement et d'entraînement. Une tête d'enregistrement et/ou de lecture peut se déplacer sur la surface du disque opposée à la surface fixe de manière à enregistrer ou à lire des informations. L'invention s'applique notamment à l'enregistrement des images de télévision et à l'enregistrement de données numériques.
