    The invention relates to the field of accumulation of information, namely, devices for rotating the magnetic head of a tape recorder. A device for rotating the magnetic head of a tape recorder, comprising a holder connected to the memory head and rotatably mounted with respect to a movable magnetic tape, is known. The device makes it possible to ensure the rotation of the magnetic head of the tape recorder relative to the moving magnetic tape with a relative length of its design ij. A disadvantage of the known device is the poor contact of the magnetic head with the movable magnesium tape. It is also known to attach a magnetic tape recorder comprising a holder, by means of which a magnetic head is mounted on a guide drum rotatably mounted with respect to a movable magnetic tape, a magnetic head displacement signal generator from a recording track, a shim and a fixing screw. This device allows for relatively good contact between the magnetic head and the magnetic tape being moved. The disadvantages of such a device are a considerable displacement of the magnetic head from the recording track, as well as a significant possibility of its breakage, which is explained by the significant inertia of the holder and its low strength. The purpose of the invention is to reduce the magnitude of the magnetic head from the recording track without any possibility of the device breaking to rotate the magnetic head of the tape recorder. This goal is achieved in that the device for rotating the magnetic head of the tape recorder, which contains the holder by means of which the magnetic head is mounted on a guide drum rotatably mounted relative to the movable magnetic tape, a magnetic head displacement signal from the recording track, padding and fixing screw , a U-shaped bar and a juice of a T-shaped juice, joined between one another, are inserted, between which the holder is placed, is made) in the form of spring metal cal njifictiny and conjugated marry, 1X with its protinopolozhnymi CToponaNm bimorftlh piezoceramic p.pastin connected to signal formir.ovatelyu bias magnetic head from the recording track and ukregshennyh between spacers to flex in a plane perpendicular naprarpeniyu recording track, wherein the U-shaped bars and the V-shaped cross section, the metal metal spring spine, the bimorph piezoceramic plates and the gaskets are made with coincident holes, in which a fastening bolt is located, ukre1scheny in the guide drum. Introducing the U-shaped and T-shaped bars into the device and making the holder in the form of a spring metal plate and bimorphic piezoceramic plates coupled to its opposite sides allows for a reduction in the displacement of the magnetic head from the recording track without increasing the possibility of breakage. FIG. 1 shows one of the possible variants of the proposed device for rotating the magnetic head of a tape recorder; in fig. 2 — Shaped and U-shaped bars and holder; in fig. 3 - the arrangement of the bars of the U-shaped and T-shaped cross section, relative to each other; in fig. 4 shows the location of the magnetic tape relative to the guide drum. The device comprises a holder 1, by means of which the magnetic head 2 is mounted on a guide drum. 3 mounted for rotation relative to a movable magnetic tape 4 and a fixed guide drum 5 adjoining it. The holder I is made in the form of a spring metal plate 6 and bimorphic piezoceramic plates 7 and 8 connected to its opposite sides and connected by leads 9, 10 and 11 to the driver of the displacement of the magnetic head 2c of the recording track (not shown). At the same time, bimorph piezoceramic plates 7 and 8 and a spring metal metal plate 6 located between them are reinforced between gaskets 12 and 13 with the possibility of bending in a plane perpendicular to the direction of the recording track. The device contains a bar 14 P-about of a different section and a bar 15 of a T-shaped cross section, between which there is a holder connected to a mif by means of gaskets 12 and 13. This bar 14 of a U-shaped cross bar 15 T -shaped section, spring metal plate 6, bimorph piezoceramic plates 7 and 8 and gaskets 12 and 13 are made with coinciding holes in which the fixing screw 16 is mounted, fastened in the guide drum 3. The operation of the proposed device is carried out as follows . The rotation of the guide drum provides rotation of the magnetic 834 of the head 2 relative to the movable magnetic tape A. It is coupled with. During the reproduction, the magnetic head 2 moves along the inclined recording tracks of the movable magnetic tape 4 applied to it during the recording process. In this case, in the process of reproducing, the shaper of the signal displacement of the magnetic head 2 from the recording track affects 5-imorph. Piezoceramic plates 7 and 8. The latter causes the bimorph piezoceramic plates 7 and B to bend in the direction of decreasing the displacement of the magnetic head 2 from the recording track. The use of the invention as compared with the base object will significantly reduce the displacement of the magnetic head from the recording track without increasing the possibility of the device breaking to rotate the magnetic head of the tape recorder.
