CA 2262653

A magnetic disk (3) is rotatably provided in a cassette shell (3) comprising an upper cassette shell half (2a) and a lower cassette shell half (2b) joined together. A magnetic head inserting hole (6) is provided in the front face (4) of the shell (2) for bringing magnetic recording and reproducing heads into contact with or close to both sides of the disk (3). Slide guide section (5) each having upper and lower slide faces (5a and 5b) which are brought into slide contact with the insertion guide members (11 and 12) of a recording/reproducing device are formed integrally with the upper and lower shell half (2a or 2b). Therefore, the vertical dimensional precision of a magnetic disk cartridge which is loaded in a recording/reproducing device of such a type that the cartridge is loaded into the device by holding the side section of the cartridge is improved.

Un disque magnétique (3) est placé rotatif dans un boîtier de cassette (3) composé d'une moitié supérieure (2a) et d'une moitié inférieure (2b) réunies l'une à l'autre. Un orifice (6) d'insertion de tête magnétique est situé dans la face avant (4) du boîtier (2) afin de mettre les têtes magnétiques d'enregistrement et de lecture en contact avec les deux côtés, ou à proximité des deux côtés, du disque (3). Des sections de guidage coulissantes (5) possédant chacune des faces coulissantes supérieure et inférieure (5a) (5b) mises en contact coulissant avec les éléments de guidage d'insertion (11) et (12) d'un dispositif d'enregistrement et de lecture, sont solidaires des moitiés de boîtier supérieure ou inférieure (2a) ou (2b). Ceci permet d'améliorer la précision de dimension verticale d'une cartouche de disque magnétique chargée dans un dispositif d'enregistrement et de lecture en retenant la section latérale de ladite cartouche.
