00 00 ten 7 Point of the Invention The invention relates to the accumulation of information, in particular to cassettes with a flexible magnetic disk. A cassette with a flexible magnetic disk is known, comprising a bag-shaped case, between which the flexible magnetic disk l is located. The known cassette protects the flexible magnetic disk from damage in the storage process. A disadvantage of the known cassette is the considerable complexity of its maintenance. . . A cassette with a flexible magnetic disk is also known. surface mounted for free rotation in the circular openings of the cheeks of the bag-shaped case 21. This cassette allows for relative Toth its service disadvantage of such cassette consisting um in considerable error Dentro Rovani floppy dika. This is due to the significant error in the installation of the drive shaft of the recording or reproducing unit in the through mounting hole of the plastic shaft of the flexible magnetic disk. The purpose of the invention is to reduce the error in centering a flexible magnetic disk. The goal is achieved due to the fact that in a cassette with a flexible magnetic disk containing a bag-shaped case between which the cheeks is located a flexible magnetic disk, concentrically mounted on a plastic shaft equipped with a magnetic pin angle sensor and arranged with a through mounting hole with a cylindrical surface and installed with the possibility of free rotation in the round openings of the cheeks of the bag package, the plastic shaft is made with a through slotted hole parallel to the axis of rotation, and the cylindrical faceted cylindrical surface of the through installation hole 8 to the drive shaft of the recording unit or the top of the through mounting hole of the plastic shaft is multi-faceted, with the through slotted hole and one of the faces of the multi-faceted cylindrical surface of the through installation hole the plastic shears are arranged in parallel, and the jumper between them is made elastic. FIG. 1 and 2 one of the possible variants of the proposed cassette with a flexible magnetic disk is shown. The proposed cassette contains a bag-like case 1, between the cheeks 2 and 3 of which there is a flexible magnetic disk 4, concentrically mounted on the plastic shaft 5. The plastic shaft 5 is equipped with a magnetic angle position pin sensor 6 and located coaxially with the magnetic ring 7, a hole 8 having a cylindrical surface and mounted in round holes 9 and 10 of cheeks 2 and 3 of package case 1. In the proposed cartridge, the plastic shaft 5 is made with a through hole 11, a pair are parallel to the axis of rotation. In this case, the cylindrical surface of the through mounting hole 8 of the plastic shaft-5 is made multi-faceted. In the proposed cassette also a through slot 11 and one of the faces of the multi-faceted cylindrical surface of the through mounting hole 8 of the plastic shaft 5 are parallel, and the jumper is made elastic, pjj are the faces 13 of the multi-faceted cylindrical surface of the through mounting hole 8 of the plastic shaft 5 are located symmetrically relative to the jumper 12 and at an acute angle to her. When the proposed cassette is mounted on a recording or reproducing unit, the drive shaft of the latter enters the through mounting hole 8 of the plastic shaft 5. At the same time, the jumper 12 is pressed into the through slotted opening 11 of the plastic shaft 5 by pressing the multi-facets 12. The latter secures and centers the plastic sleeve 5 on the drive shaft of the recording or reproducing unit. The use of the invention in comparison with the base object allows 103810 to significantly reduce the error in centering the flexible magnetic disk due to the fact that the plastic shaft is made with a through slit hole parallel to the axis of rotation.
