01 The invention relates to instrumentation, in particular, to a device with which it is possible to record digital information signals on magnetic media. A device for digital magnetic recording is known which contains successively connected a coding block, a register, a pulse counter, and a reference frequency generator. The device also used a decoder. a trigger., a recording amplifier and a C 3 magnetic head connected to it. This device works reasonably well only when recording does not require the conversion of digital information signals into analog signals. Otherwise, the design of the device requires substantial complexity. Closest to the invention is a digital magnetic recording device comprising signal sources, a serially connected analog converter, a shift register, a faint information recording and a magnetic head, as well as a reference clock generator, the output of which is connected to the shift input of the shift register, and a pulse counter, the input of which is connected to the output of the reference frequency generator, and the output is connected to the receive input of the shift register code 2 ;. However, the known device, although it allows using signals of a different kind, is nevertheless difficult with its help, and sometimes it is simply impossible to simultaneously record signals from different sources on one track. The purpose of the invention is the realization of the possibility of simultaneous recording of signals from different sources on one track. This goal is achieved in that a digital magnetic recording device containing signal sources connected in series analog-code converter, shift register, information recording unit and magnetic head. as well as a reference frequency generator, the output of which is connected to the shift register shift input, and an impulse counter, whose input is connected to the reference frequency generator, and the output is connected to the receive input terminal Yes, the shift register, the second pulse counter, the decoder, the keys connected to its different outputs and the separate connected to the outputs of all the keys an adder, whose output is connected to the converter with an analog code, are entered in series; each source of the signal is connected to the second input of the corresponding key ., and the outputs of the second pulse counter are connected to the register inputs of the shift register. The drawing shows the structural scheme of the device, the device uses keys 1, the outputs of which are connected through an adder 2 to the converter 3 analog-code, and the inputs are connected to a counter of k pulses through a decoder § A counter of 7 pulses and a generator 8 are connected to different inputs of the shift register 6 the reference frequency, the output through the recording unit 9 is connected with the magnetic head 10. From the sources of 11 signals, input analog signals are sent to the individual inputs of the keys 1. During operation of the device, the counter B gives the command to open is one key and then the signal that passes through this key is fed to the input of the converter 3- In turn, the counter 7 and the generator 8 for-. another command, which allows the signal received at the output of converter 3, to be entered into register 6. At the same time, the counter code data is entered into the register. Then it becomes possible, using pulses of the reference frequency received from generator 8, to shift the code in the register Then, after passing through the recording unit, this final signal is recorded on magnetic media 12. When counter 7 is triggered, the conversion factor of which is equal to the number of bits of register 6, the state of counter 4 changes by one itsu. This allows the counter to issue a command to open the next key, which ultimately allows the digital equivalent of the analog signal to be recorded, taking into account its number, determined by the state of the counter. As a result, it is possible to simultaneously simultaneously record digital information.
