ABSTRACT OF THE DISCLOSURE In a magnetic recording circuit with a bias cur- rent circuit adapted to superimpose a bias current from a bias oscillator on a recording signal and to supply a resultant signal to a magnetic head, there is provided a resistor for detecting the bias current flowing through the magnetic head, a rectifier circuit for rectifying and smoothing a signal developing across the resistor, and a control circuit for comparing the output voltage of the rectifier circuit with a reference voltage and producing an output signal which controls the oscillation level of the bias oscillator, whereby the bias current flowing through the magnetic head can automatically be set to a predetermined level. A variable resistor for adjustment of the bias current and adjustment step for the variable resistor can be dispensed with.
