Abstract

PURPOSE: To ensure the detecting operation of the detection signal at reproduction, by recording the detection signal in different frequency depending on the presence of the use of the noise reduction circuit and forming the no-signal section before and after the recording position.
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, 6 the one-shot multivibrators 15, 16, 18 are inverted, and the switches 24, 25 are switched with the operation of the transistor 23. Simultaneously, the muting transistors 42, 43 are operated and the recording operation of the detection signal in different frequency from the oscillation circuits 29, 36 is controlled. Accordingly, no-signal sections P, Q are formed before and after the recording position of the first and the second detection signal on magnetic tape, allowing to ensure the detection operation when the presence of use of the noise reduction circuits 5, 6 is detected at reproduction.
