The present invention provides a cartridge accommodating a disk therein which is inserted into a cartridge holder, the cartridge holder being provided with a mis-insertion protection member. The mis-insertion protection member is located within an insertion path along which the cartridge is inserted into the cartridge holder. The cartridge has a substantially rectangular shape. The cartridge has a corner portion at each of four corners of the substantially rectangular shape, the corner portion being shaped so as to abut on the mis-insertion protection member to move the mis-insertion protection member out of the insertion path. The cartridge has at least two mis-insertion protection mechanisms for engaging with the mis-insertion protection member so as to prevent the cartridge from being mis-inserted. The cartridge has two side surfaces which are substantially perpendicular to a surface of the disk and extend along a direction substantially parallel to a direction in which the cartridge is inserted into the cartridge holder. A mis-insertion protection mechanism of the at least two mis-insertion protection mechanisms is provided on each of the side surfaces.
L'invention concerne une cartouche dans laquelle on peut placer un disque inséré dans un support comportant un élément de protection contre une mauvaise insertion. L'élément de protection est disposé dans le trajet d'insertion suivant lequel la cartouche est insérée dans le support. La cartouche, de forme sensiblement rectangulaire, comporte à chacun de ses quatre coins une partie angle formée de façon à buter sur l'élément de protection et à le faire sortir du trajet d'insertion. Elle comporte au moins deux mécanismes de protection qui entrent en contact avec l'élément de protection et empêchent une mauvaise insertion de la cartouche. Elle présente deux faces latérales sensiblement perpendiculaires à la surface du disque et disposées dans un plan sensiblement parallèle au plan d'insertion de la cartouche dans le support. Chaque face latérale comporte au moins un mécanisme de protection contre une mauvaise insertion.
