摘要：In a magnetic recording apparatus or magnetic recording/reproducing
apparatus having a frequency modulator for frequency-modulating an information signalto be recorded in a recording system, a reference signal is recorded and reproduced so
that recording or reproducing characteristics of the information signal are controlled inaccordance with a level of the reproduced reference signal, whereby the recording orreproducing characteristics can be set so as to match a characteristic of a magneticrecording medium. In this apparatus a DC-voltage source for selectively supplying apredetermined level of a DC-voltage to said frequency modulator is provided so that anoutput of said frequency modulator obtained by supplying the DC-voltage to saidfrequency modulator is used as the reference signal.
