る磁気テープの感度補正回路。 In a two-head type magnetic recording/reproducing device, the output signal of an oscillator is recorded on a magnetic tape through a recording amplifier, the recorded signal is reproduced, the level of this reproduced signal and the output signal of the oscillator is compared, and these signals are recorded. The recording level is adjusted by changing the gain of the recording amplifier by the same amount as the level during recording and playback when playing back the above-mentioned recorded signal so that the level has a predetermined relationship. Magnetic tape sensitivity correction circuit.
