    The invention relates to the accumulation of information, in particular to tapes with tape media. A cassette with a recording medium is known, which contains a case-like casing, between which cheeks are located cores located in rolls of a tape recording medium. The cassette with the relative simplicity of the design provides in the process of recording and reproducing tape rewind recording from one core to another lj. A disadvantage of the known cassette is the considerable complexity of its maintenance. Also known is a cassette with a tape recording medium containing dust-proof case-like skin with deaf holes in the cheeks, in which bearings are installed, in which the ends of the shafts rigidly connected to the core and coils made of magnetic material and arranged in rolls of tape carrier are placed. This cassette allows for relative ease of maintenance 2. The drawback of the cassette is that there is a significant possibility of damage to the recording media due to smoldering from the cores of the coils, since the cores of the coils can be twisted in a free state. The purpose of the invention is to reduce the possibility of damage to the tape recording media due to unwinding from the cores of the coils. The goal is achieved by having a cassette with a tape recording medium containing a dustproof case. Rhodian casing, with deaf holes in its cheeks, in which bearings are fixed, in which the ends of the shafts rigidly connected to the cores of the coils, made of magnetic material and located in rolls of the recording medium, are placed, annular constants are inserted, mounted in the first cheek dustproof case | casing with the ability of the cores of the coils to be mated before mating, and the second cheek of a dust-proof case-like leather-55 floor
    Xa has the means of positioning it relative to the sources of the magnetic field unlocking and rotating the KaryuieK cores. In this case, the means of positioning the second cheek relative to the sources of the magnetic column of the coils, the shafts being mounted with the possibility of axial movement in the bearings, and the length of each shaft is less than the distance between the outer ends of the bearings. Moreover, the means of positioning the second cheek relative to the sources of the magnetic unlocking field and rotating the cores of the coils on the second cheek of the tight-fitting casing can be executed in the form of sector-like holes, the end {tritichno distributed around the shafts. The proposed cassette due to the insertion of annular permanent magnets into it, and also due to the fact that the shafts are mounted with the possibility of axial displacement (in the bearings, it greatly reduces the possibility of damage to the recording media due to winding from the cores of the coils. FIG. Fig. 1 shows a cassette with a tape recording medium; Fig. 2 shows the second cheek of a dustproof case-shaped case, Fig. 2 shows the arrangement of a shaft in bearings. The proposed cassette contains a dustproof case-shaped box. uh 1, which has in its first 2 and second 3 cheeks deaf holes, in which bearings 4 and 5 are rigidly fixed. The ends of the shafts 6, rigidly connected to the cores 7 of the coils made of magnetic material and arranged in rolls, are placed in the under-slip 4 and 5. 8 tape recording media. The shafts 6 are mounted for axial movement in bearings 4 and 5. At the same time, the length of each shaft 6 is less than the distance between the outer ends of the bearings 4 and 5. The proposed cassette also contains annular permanent magnets 9 mounted in the first the cheek 2 of the dust-proof case-like casing 1, with the possibility of attracting the cores 7 of the chair-liners before mating with them. The second cheek 3 of the dust-proof case-like casing 1 has means of positioning relative to the sources of magnetic unblocking and rotation of unblocking and adhesion. The core 7 of the coils is made in the form of sectoral different holes 10 concentric with the shafts 6. When storing the proposed cassette and recording or playing it, following. If the proposed cassette is located 1 t g outside the cassette receiver of the tape mechanism, the cores 7 are coils and are coupled with ring permanent magnets 9 due to the attraction from the latter. As a result of this, the turning of the cores of the 7 coils is prevented, and consequently, the spontaneous unwinding of the tape recording medium. 474 After installing the transducer cassette into the cassette receiver of the tape mechanism, the sources of the magnetic field for unlocking and rotating the cores of the 7 cores ensure the removal of the latter from the ring permanent magnets 9. In addition, they provide rotation of one core 6 of the coil and braking of the other. As a result, the tape recording media is moved and rewound from one core 7 of the coil to another. The use of the invention makes it possible, in comparison with the basic object, to significantly reduce the possibility of damage to the tape recording medium due to winding from the cores of the coils.
