    A thin flexible magnetic disk rotatably disposed in a cartridge of rigid material and protected thereby. The disk is loosely mounted on a driving hub assembly and has an arrow shaped center hole surrounding a central round hub portion of the hub assembly. A drive pin is carried by the hub assembly and extends loosely through a corresponding hole located in the disk and spaced from the center of the hub assembly and located on a radial line preferably of about 90 degrees with respect to a radial line passing through the apex of the straight hole edges forming the arrow so that the disk is automatically centered on the hub assembly due to any restraint on the disk during its rotation.

    one .
    The invention relates to the accumulation of information, namely to magnetic disk cartridge.
    A known magnetic disk cartridge comprising a rectangular case with a circular cavity, in which a magnetic disk is disposed.
     The known construction is relatively simple, but does not provide sufficient ease of maintenance.
    A cassette with a magnetic disk is also known, which contains a core mounted in a rectangular case with the possibility of fitting its conical cavity on the conical surface of the motor shaft and made with a flange-shaped protrusion located on its front surface. against the flat surface of the magnetic disk and with a cylindrical bead located in the central hole of the magnetic disk and in the washer element 12.
    This cassette allows for relative ease of maintenance. The disadvantage of such a cassette is E, a significant error in centering the magnetic disk,
    The purpose of the invention is to reduce the fault rate of centering the magnetic disk "
    The goal is achieved by the fact that the washer-like element is made with round L "lindrichskimn 'protrusions to the upper-flange-shaped protrusion of the core provided with a ledge protrusion and the magnetic disk is made with additional round holes and with a lead aperture, and the cylindrical core flange with the central hole of the magnetic disk in two spaced points; with the formation of gaps between them with its diametrically opposite sides, and the leading ledge of the flange-shaped protrusion of the core is placed in the cut-out of the washer element and in the driver-hole of the magnetic disk in the additional round holes of which are placed the round cylindrical protrusions of the washer element
    The cylindrical bead can also be made round, and the central hole of the magnetic disk can be made with large sections.
    In addition, a cylindrical bead can be made with protrusions, and
    05789
    the central hole of the magnetic disk is round.
    FIG. 1 shows one of the possible variants of the proposed cassette.
    5 with magnetic disk; in fig. 2 - core; in fig. 3 and 4 - variants of the magnetic disk.
    The proposed cassette comprises a core 1 mounted in a straight, Q coal case 2 with the possibility of fitting its conical cavity 3 on the conical surface 4 of the motor shaft 5. The core 1 is made with a flange-shaped protrusion 6, located on its end surface against the flat surface of the magnetic disk 7, and with a cylindrical collar 8. The cylindrical bead 8 of the core 1 is located in the central 2JJ of the magnetic disk 7 and in the washer element 10, made with circular cylindrical protrusions 11 and with a cut-out 12. In this case, the flange-shaped protrusion 6 of the core 1 is provided with a lead protrusion 13, and the magnetic disk 7 is made with additional round holes 14 and with a powered hole 15. In the constant tape core cylindrical collar 8 conjugated 1 - women with -central otverstmem magnetic disk 9 7 Melting two spaced apart to form gaps therebetween with its two diametrically opposite sides. At the same time, the buoyant vystuk 1.3 of the flange-shaped protrusion 6 of the core 1 is placed in the notch of the washer-shaped element 10 and in the lead-in hole 15 of the magnetic disk. The circular cylindrical projections of the 10-bi-FID element 10 are placed in an additional round shaft of the magnetic disk 7. Cyclopric 14 "8th bead core t
