    The invention relates to magnetic recording, in particular, to devices for digital magnetic recording of sound signals. A device for digital magnetic recording of sound signals is known, which contains modulators, the outputs of which are connected via recording amplifiers to recording heads Cl3. The known device allows digital digital recording of audio signals with the relative simplicity of its design. A disadvantage of the known device is that it does not allow a high density of digital magnetic recording of audio signals. It is also known a device for digital magnetic recording of audio signals containing information modulators, whose outputs are connected through recording amplifiers of information signals with recording heads. information signals, a control modulator, the output of which is connected through a control signal recording amplifier with a control signal recording head, input buses of information codes ion signals, an input format signal bus, the input bus signal samples and the discrimination of the clock input bus clock signal 21. This device allows a relatively high density digital magnetic recording ulcer postglacial signals. The disadvantage of this device is the significant error of the digital-magnetoy recording audio signals. This is due to errors resulting from distortions specific to the magnetic recording process. The purpose of the invention is to reduce the error of a digital magnetic recording of audio signals. The goal is achieved due to the fact that a device for digital magnetic recording of audio signals containing information modulators, which are connected via recording amplifiers of information signals to information signal recording heads, a control modulator, the output of which is connected via a recording amplifier control signal recording head, input buses of information signal codes. input format signal bus, input sampling signal bus on the clock clock input bus, a formatted record distributor, whose outputs are connected to the information modulators inputs, a CODES driver with the address of sectors and recording blocks, the first output of which is connected to the control modulator input, and outputs to the input bus of the format signals, to the input bus of the sample identification signals and to the input bus of the clock sync signal, corrective converters of the recording codes whose inputs are connected with input buses of information signal codes, and a record address selector, the second output of the sector address codes generator and recording blocks connected to corrective transducers of write codes connected to the input signal bus of a format connected to the input of the record address selector connected by the output to a format distributor records In addition, in the device for digital magnetic recording of audio signals, the shaper of sector address codes and recording blocks is made in the form of a multi-bit counter. The drawing shows one of the possible variants of the proposed device for digital magnetic recording of audio signals. The proposed device contains information modulators 1, the outputs of which are connected via amplifiers 2 recording information signals with heads 3 recording information signals coupled to a magnetic recording medium (not shown), control modulator 4 and format recording distributor 5. A control modulator 4 is connected via an output through a control signal recording amplifier 6 to a control signal recording head 7 coupled to a magnetic recording medium. Record formatting distributor 5 is connected by outputs to the inputs of information modulators 1. The proposed device also contains shaper 8 address codes and recording blocks, the first output of which is connected to the input of control modulator 4, and inputs to the input bus 9 of format signals, input bus 10 of the signals identifying samples and to the input bus 11 of the sync signal, corrective converters 12 write codes, the inputs of which are connected to the input buses 13 codes of information signals. The second output of the imaging unit 8 codes of addresses of sectors and recording blocks is connected and corrected Giruing converters 12 write codes connected to the input bus 9 format signals connected to the input of the selector 14 of the address record connected to the format distributor 5 records. In this case, the shaper of codes of addresses of sectors and recording blocks can be made in the form of a multi-bit counter. Digital magnetic recording of sound signals through the proposed device is as follows. Each of the correction transducers 12 write codes generates a digital code in accordance with signals from the second output of the imaging unit 8 sector address codes and recording blocks and from the input bus 9 format signals. The digital codes from the outputs of the correction transducers 12 write codes are fed to the inputs of the format distributor 5 records, which redistributes them to their outputs in accordance with the control signal generated by the selector 14 of the write addresses on the signal supplied from the input bus 9 format signals. Digital signals from the outputs of the format recording distributor 5 are fed to the inputs of the information modulators 1. The modulation results from the outputs of the information modulators 1 pass through the amplifiers 12 of recording information signals to the heads 3 of recording information signals. The shaper 8 sector address codes and write blocks also produces a control signal, which from its first output is fed to the input of control modulator 4. The result of modulation from the output of control modulator 4 is fed through amplifier 6 of control signal recording to recording head 7 control signal. The proposed device, by introducing a recording format distributor, a sector address code generator and a recording unit, 1) rectifying recording code converters and a recording address selector, can significantly reduce the error of a digital magnetic recording of audio signals.
