SIGNAL REPRODUCING DEVICE

PROBLEM TO BE SOLVED: To provide a signal reproducing device for reducing the number of bias conductors by using two bias conductors for analog signal reproduction also for digital signal reproduction. SOLUTION: Changeover switches 23 and 24 are switched during reproducing of a digital signal and bias voltages set by resistors 25 and 26 are supplied to bias conductors 21 and 22. The changeover switch 23 is switched during reproducing of an analog signal, reproducing signals amplified by signal amplifiers 15 and 16 are passed through feedback coefficient calculators 17 and 18 and amplifiers 19 and 20, currents are supplied to the bias conductors 21 and 22 and thus, the bias conductors 21 and 22 are shared.
