Abstract

PURPOSE: To automatically detect the presence of the use of noise reducing circuit, by detecting the detection signal at reproduction through the recording of the detection signal in different frequencies on magnetic tape depending on the presence of use of the noise reduction circuit.
CONSTITUTION: When the signal of left and right channels 1 and 2 close the operation switch 17 during recording with the magnetic heads 9, 10 via the noise reduction circuits 5 and 6, the one-shot multivibrations 15, 16 and 18 invertingly operate and the switches 24, 25 are switched with the operation of the transistor 23. Simultaneously, the muting transistors 42, 43 are operated to control the recording operation of the detection signal in different frequency from the oscillation circuit 29 and 36. Accordingly, the first or the second detection signal is recorded on magnetic tape in following to the no-signal section P, and the presence of the use of the noise reduction circuits 5 and 6 can be detected by detecting the detection signal at reproduction.
