Abstract

L'invention concerne une cassette de bande d'enregistrement magnétique. Elle comporte, de chaque côté des galettes de bande, une feuille de glissement assurant un enroulement uniforme de la bande sur le moyeu. Cette bande de glissement comporte au moins trois nervures convexes, en matière spéciale, disposées radialement par rapport aux deux trous de réception de broches d'entraînement Les extrémités de ces nervures sont fermées et elles sont disposées dans des positions telles qu'elles évitent toute fluctuation du noyau et de la galette pendant l'enroulement de la bande. L'invention s'applique notamment aux cassettes du type Phillips.
