METHOD AND DEVICE FOR REPRODUCING SIGNAL

PROBLEM TO BE SOLVED: To reproduce a signal on electromagnetic conversion with different required band characteristics satisfactorily (by improving C/N) by using the same head and a rotary transformer, and to prevent costs from being increased and constitution from being made large-scaled. SOLUTION: At the time of reproducing a digital signal or an analog signal from a magnetic tape by using the same head rotary system 3, an additional capacitance Cs included in a resonance capacitor Ct is controlled by a mode control signal mc corresponding to which of the analog signal and the digital signal should be reproduced so that head resonance frequencies decided from an equivalent inductance Lt of the head rotary system 3 and the resonance capacitor Ct can be varied. Also, when any distortion is developed in signal amplitude and a phase due to the variation of the head resonance frequencies, a feedback gain Ka of feedback dumping is varied or switched from the mode control signal mc so that optimization can be attained.
