Abstract
PURPOSE: To provide the reproducing tone close to the original tone by controlling the magnitude of the reproducing tone with the reproducing signal of the signal indicating the magnitude of the original tone having been recorded in the second track.
CONSTITUTION: The original tone from a microphone 10 is recorded in the first track of tape with a mian head 6 via AGC circuit 11 and a the same time it is converted to a d.c. signal in a rectifier circiut 15. This signal is then applied to the limit circuit 16 provided with a diode 17 to which a reference voltage V1 is applied. Then, when the original tone is below the specified magnitude, the diode 17 goes ON and when the reference voltage is above the same, the output voltage of the circuit 15 is recorded as control signal in the second track of the tape by way of an auxiliary head 7 via amplifier 18, voltage-frequency conversion circuit 19, etc
