    FIG. 1 shows one of the possible options preg.lagaemsg. a device for controlling the nc / pe ie the tape carrier of the zipper relative to the rotating magnetic head; in fig. 2 - block of the reversed magnetic head.
    The device comprises a power amplifier 1 connected to an output to an electric motor 2, the shaft of which is mounted to mate with a tape carrier 3 for recording, for example a magnetic tape. At the same time, the tape recording medium 3 is mounted to the movable along the helical line relative to the rotating magnetic head unit 4. The latter has guide drums and 6, between which the rotating magician 4 is mounted with a pair of recording media 3, moving through the motor shaft 2.
    The shaft of the electric motor 2 is kinematically connected to a tachometer 7 connected by an output to the first input of the comaiarator 8. The second input of the mapa 8 is connected to the output of a controlled oscillator 9 of a signal of a given slow motion speed, KoTopbDi can be performed on an operational i amplifier.
    The device also contains a switch 10 made with a control input and connected to the input of power amplifier 1, and a block 11 for comparing a rotation speed signal
    the reference voltage connected to the input from the output of the tachometer 7. In this case, the block 11 for comparing the rotation speed signal with this voltage can be performed on the comparator and on the reference voltage driver.
    In addition, the device contains on: e sequentially block 12 synchronization time interval,
    having a reset input, and a generator of 13 pulses of variable duration, made with a counting input connected to a tachometer 7, and a block 12 of sync1; from the time interval it can be made on a transistor current source and a multivibrator with one steady state, and the generator 13 them: 1 Ls of variable ditiness - on the element AND-NOT, the counter and inverters.
    The device works in a manner.
    When recording and reproducing, the rotation of the shaft of the electric motor 2 is converted into translational movement of the recording medium 3 relative to the rotating magnetic head 4, In the recording process, the rotating magnetic magnetic head 4 applies the recording tracks to the recording recording medium 3. In the process of reproduction, the control of the movement of the recording tape medium 3 is realized, ensuring the installation of the rotating magnetic head 4 on the recording tracks applied during recording. When the recording medium is moved 3, the tachometer 7 generates a signal characterizing the lean speed of rotation of the motor shaft 2. The signal of the tachometer 7 is fed to the comparator B, which also receives a J11 signal from the controlled oscillator 9 of the signal at a given slow motion speed. The comparator 8 generates a voltage applied to the switch 10, controlled by a batch 11 of comparing the rotational speed signal with the reference voltage. A switch 10 is also supplied from the output of the generator of 13 pulses of varying duration, to which the signal of the tachometer 7 arrives. Depending on the speed of rotation of the shaft electr. 6 rohvig-tel 2 switch 10 provides the input to the amplifier 1 MouiHocTH or the signal of the comparator 8 or the signal of the generator 13 pulses of variable duration. The use of the invention as compared with the base object allows to significantly reduce the error in controlling the movement of the tape recording medium relative to the rotating minimum unit;
