FIELD: analog magnetic recording equipment. SUBSTANCE: device has record amplifier 1, lower frequency filter 2, adders 3, controlled-gain amplifier 6, amplitude detector 7, full-wave rectifier 9, reference voltage source 10, biasing generator 11. Residual biasing may be increased by 5-6 dB at low frequencies and distortions may be reduced 2-3 times as many. At higher frequencies dynamic distortions may be reduced 2,5-3 times and dynamic range may be widened by 5-7 dB. EFFECT: improved efficiency; improved precision of data recording. 4 dwg
