    The invention relates to magnetic recording, and in particular to devices for manufacturing a magnetic recording medium.
    A device for manufacturing a magnetic recording medium comprising a magnetic dispersion deposition unit on the surface of a non-magnetic flexible tape base is known. The known device has a relatively simple design [1].
    A disadvantage of the known device is the significant edge growths of the tape-like layer of magnetic dispersion deposited on a non-magnetic flexible tape base in the manufacturing process of the magnetic recording medium.
    It is also known a device for manufacturing a magnetic recording medium containing a magnetic dispersion deposition unit on the inner surface of a non-magnetic flexible tape base installed with the ability to move relative to the edge growth element of the edge growths of the tape-shaped magnetic dispersion layer, the width of which is less than the non-magnetic flexible tape base. The known device provides the elimination of tape growths of the tape-like layer of magnetic; variance [2].
    A disadvantage of the known device is the considerable complexity of the manufacturing process of the magnetic recording medium.
    The purpose of the invention is to simplify the manufacturing process of a magnetic recording medium.
    This is achieved due to the fact that the element for eliminating the edge growths of the ribbon-like layer of magnetic dispersion is located on the side of the outer surface of the flexible ribbon base and is made in the form of a permanent magnet and magnetically soft elements connected to its opposite poles, between which there is a working gap having a length of 10-200 mm and a width of 0.5-2.0 mm, the angle between the axial line of the working gap and the edge of the ribbon-like layer of the magnetic dispersion is 0.510.0 °, and the magnetic induction in the magnetic dispersion is opposite to the working Zora is 500-1800 gauss.
    Figure 1 shows one of the possible variants of the proposed device for magnetic recording; on the.
    FIG. 2 - the location of the element to eliminate the edge growths of the ribbon-like layer of magnetic dispersion.
    The device comprises a node for applying magnetic dispersion onto the inner 5th surface of a nonmagnetic flexible tape base 1 (not shown). In this case, a non-magnetic flexible tape base 1 is installed with the possibility of movement relative to the element 2 of the elimination of the edge growths 3 of the ribbon-like layer 4 of the magnide dispersion. Moreover, the width of the tape-like * layer 4 of the magnetic dispersion is less than the width of the non-magnetic flexible tape base 1.
    In the device element removing excrescences edge 3 of band-shaped magnetic layer 4 is configured in the form of a dispersion of the permanent magnet 5 and interfaced with its proti- 20 vopolozhnymi poles magnetically soft conductive members 6. Between magnihno-soft conductive members 6 located working air gap 7 having a length of 200 mm and a width of 2.0 mm. At 25, the angle between the axial line of the working gap 7 and the edge of the tape-shaped layer 4 of the magnetic dispersion is 0.5 °, and the magnetic induction of the magnetic dispersion against the working gap 7 is 1800 G.
    In the device, in the process of manufacturing a magnetic recording medium, a tape-like layer 4 of magnetic dispersion is deposited on a non-magnetic flexible tape base 1 movable j 35,. In addition, the effect of a constant magnetic field of the working gap 7 on the edge growths 3 of the ribbon-like layer 4 of the magnetic dispersion 40 is provided. ' The latter leads to the elimination of the edge growths 3 of the tape-shaped layer 4 of magnetic dispersion due to the smearing of the latter on the inner surface of the non-magnetic flexible tape base 1.
    The use of the invention allows to greatly simplify the manufacturing process of the magnetic recording medium.
