    A cantilevered beam assembly with a maximum resonance frequency is adaptable for supporting a transducer for use with a random access flexible disk file. The cantilevered beam assembly includes a first cantilevered member and a second elongated member coupled at one end by a flexible joint to the free end of the first cantilevered member. When used with a flexible disk file system, a magnetic transducer is seated on the second end of the elongated member while said elongated member is restricted to flex in one plane only. A relatively thin, tapered, elongated protective structure having a relatively sharp, elongated leading edge contiguous with a relatively sharp front edge is rigidly connected to the first cantilevered member and surrounds the second elongated member in a plane orthogonal to the plane of flex.

    In addition to this, the length of the x-rays of the rectangular plastic base can be the length of a quarter of an olive holder from its end to the hinges, and the protective element can be made with a sharp outer 5 edge.
    On (Ling. 1 and 2) different types of one short-circuit of possible variants of the proposed device for moving the soft head between magnetic disks are shown.
    The device comprises a rectangular plate base I rigidly fixed on a carriage (not shown), a holder 2 on which a magnet is mounted on the head 3, and a hinge 4. At the same time, the hinges strengthened “1y between the rectangular Lamellar base 1 and the holder 2.
    The rectangular plate base 20 1 is provided with cantilever protrusions 5, symmetrically with which the holder 2, made crosswise, is fixed. The holder 2 is installed; the kn is inside a security element, made in the form of a zugi bis 25 with a sharp outer edge 7, with the possibility of oscillations perpendicular to the planes of magnetic disks (not shown). Arc 6 is symmetrically and rigidly fixed with its ends on a rectangular plate-shaped base 1. At the same time, it is straight | The lamellar base 1 is an element of the bevel 8, mated with one end of the spring 9, complete in the form of a package-plate springs and symmetrically fixed by the other j end to the holder ii.
    The length of the cantilevered arms 5 of the rectangular lamellar base 1 is equal to a quarter of the length of the holder 2 from it to the hinges 4.
    Moving the carriage leads to the introduction of the magnetic head 3 into the gap between the magnetic disks of the class and its removal from it. At the same time, the protective element in the process of insertion and removal of the magnetic head 3 ensures that it is not damaged and that the magnetic disks are damaged. The design of the holder 2 and its fixation on the rectangular plate base 1 provide an increase in the frequency of 5 pQr0a1c; and natural oscillations, /

    l structures and the location of the spring 9 reducing their amplitude. The latter allows to significantly reduce the error in the movement of the magnetic Golski between the magnetic disk act.
    The use of the invention also allows for a considerable simplicity of the process of managing this movement.
