PURPOSE:To prevent generation of a flicker by connecting a band correction circuit compensating a high or low or high/low frequency of a field reproducing signal to either a non-delay signal path or a delay signal path. CONSTITUTION:An amplifier 2 is connected to a magnetic head 1 and the non- delay signalpath A and the delay signal path B are connected in parallel between the amplifier 2 and a field frame changeover switch 3 provided at the post-stage. The delay signal path B consists of the amplifier 2, and sequential connection of a capacitor 4, a glass delay line 5, an amplifier 6, a band correction circuit 7. The band correction circuit 7 uses the glass delay line 5 to compensate the attenuated band and the band of the field reproducing signal via the non-delay signal path A and the field reproducing signal via the delay signal path B are similar and no flicker takes place.
