-05 The invention relates to instrument engineering and can be used for recording information on recorders with reciprocating motion of a writing element and operating in a standby mode. A recording device on a tape containing a synchronizer connected in series, an electromechanical scanning device with a reciprocating motion of a writing element, a recording amplifier and a unit for converting ultrasonic vibrations into electrical signals fll are known. The disadvantage of the device is the presence in the electromechanical device of the accelerating zone of a writing element in which the speed of the latter varies within large limits before reaching the desired constant speed, therefore part of the recording medium coming to the acceleration zone is usually not used, since it is displayed in its information is largely distorted. . . The closest in technical essence to the present invention is a rectifier with a reciprocating movement of the pen, which contains a control unit, the input of which is connected to the input of an electromechanical spreading device. The recorder synchronizer detects the signals that move the recording medium and the writing element. According to the trigger signal, the writing element, moving across the recording medium, carries information arriving on the second from the amplitude-frequency processing unit of the seismic signal, and then returns to its original position, waiting for the next trigger signal 2. A disadvantage of the known recorder is the presence in the electromechanical the sweep device of the acceleration zone of the writing element, at which the speed of its movement, before reaching the constant value, varies within the limits of This is due to the fact that the electric motor is not moving the squeaking element cannot instantly reach the specified rotational speed, as well as the presence of the moment of inertia of the mechanical drive hubs, which transform the rotational movement of the motor shaft into a linear movement of the writing element. The part of the recording medium, within which the speed of movement of the writing element reaches its value, is usually not used due to large distortions when recording information in it. The width of this part of the recording medium grows with an increase in the speed of the screw and at high values of the latter can be up to 25% of the entire width of the recording medium, which leads to a decrease in the recording medium of the recording medium and a decrease in the amount of information recorded on this recording medium. The purpose of the invention is to increase the utilization rate of the working field of the recording medium and to increase the amount of information recorded per unit of time. The goal is achieved in that a device containing a control unit, the output of which is connected to the input of an electromechanical sweep device, is inserted in series with a block for separating the acceleration run zone, an information conversion unit in the recording parameter, the output of which is connected to the electromechanical input a sweep device, the input of the block for allocating the accelerating zone of the forward stroke being connected to the output of the control unit. In addition, the block of the acceleration zone of the forward stroke is designed as a trigger and a decoder, the outputs of which are connected to the inputs of the AND circuit, while the inputs of the trigger and decoder are the inputs of the block of the acceleration zone. FIG. 1 shows a registrar circuit; on (| ig. 2 is a diagram of the block for allocating the acceleration zone of the forward stroke; Fig. 3 shows time diagrams of the recorder operation. The recorder contains a control block 1, an electromechanical sweep device 2 with an input terminal 3, a block 4 that converts information into a recording parameter input cream 5 and block 6 for allocating the acceleration zone of the forward stroke, the output of which is connected to the input of the electromechanical sweep device 2 through the information conversion unit 4 to the recording parameter, the other input of which is connected to the output of the control unit 1, The coils of the output of the disengagement zone of the forward stroke connected to the inputs of the unit 6. The recorder works as follows: According to commands from the control unit 1 in the electromechanical scanning device 2, the recording medium is moved, as well as the reciprocating movement of the writing device Thus, on command from control unit 1 (Fig. 3, 3), p for a time t C etsc forward sweep stroke, i.e., movement of the writing element across the recording medium. Then, at the command of the control unit 1 (Fig. 3.3.2), during the time tQ, the writing element performs a reverse stroke, i.e. returns to its original position and waits for the next command from control block 1. During the forward stroke, the writing element records information arriving at the input of the electromechanical scanning device 2 through a terminal. 3, and in the initial part of the recording medium, in the acceleration zone that the writing element passes during the time tp3 (Fig. 3.3.1) and in which its speed varies over a wide range before reaching a given constant value, is recorded due to significant distortions due to a change in the scanning speed in this zone. On the return stroke, the writing element, as well as on the forward stroke, accelerates during the time tpt. and then it moves at a constant speed, i.e. a writing element unused on the run of the recording medium passes at a constant speed. Block 6 for allocating the accelerating zone of the forward stroke produces at the moment of time t to) (- tpT on the reverse run a signal (Fig.3,3.5), the temporary position of which corresponds to the end of the accelerating zone on the forward stroke (with equal speeds of forward and reverse This signal triggers information conversion unit 4. In the recording parameter, the signal from the output of which is fed to the electromechanical scanning device 2 is recorded on the reverse side of the writing element in the forward run up zone. via terminal 5, while the conversion unit 4 converts it, for example, during time intervals, displayed on the recording medium as strokes with length information corresponding to the values, or into short pulses displayed as labels synthesizing a line in several sweeps, the removal of which points from the beginning of the zone is proportional to the magnitude of the information, or to a sequence of pulses that ensures the display of decimal numbers, letters, characters for several cycles of movement of the writing element, or signals dp tobrazheni information in another desired form. Block 6 of the selection of the acceleration zone of the forward stroke contains (Fig. 2) trigger 7, decoder 8 and circuit 9, the inputs of which are connected to the output of trigger 7 and the output of the decoder 8. On command from the control unit 1 about the beginning of the forward stroke of the writing element (Fig.3.3.1) the trigger 7 switches (Fig.3.3.3), while its output signal closes the AND 9 circuit for the duration of the forward stroke of the writing element. From control block 1, a digital code is received at the input of the decoder 8, which determines the location of the writing element on the record carrier both on the forward and reverse course. At the output of the decoder 8, pulses are formed in the reverse direction (g. 3, 3, 4), and the temporary position of the output pulse of the decoder 8 during the return stroke corresponds to the end of the acceleration zone of the writing element n, and the forward stroke. Upon a command from the control unit 1 on the beginning of the return stroke of the writing element (Fig.3.3.2), the trigger 7 is reset to the initial state (Fig.3.3.3). The signal from the output of the trigger 7 permits the passage through the AND 9 IMA circuit: the pulse from the decoder 8 generated by it during the return stroke (Fig.3.3.5). This impulse goes to conversion unit 4 and starts it. Thus, the proposed recorder allows to record information in the acceleration zone of the forward stroke of the recording medium during the reverse stroke of the writing element. The use of new elements of the information conversion unit in the recording parameter and the block of the forward stroke acceleration zone selection made in the form of a trigger, a decoder, and
