Abstract

PURPOSE: To realize a high-fidelity recording/reproduction even in a low tape speed, by dividing the record signal into frequency bands with the crossover frequency of 3W7KHz and then recording the divided signals with the bias current of a smaller value than the bias current which mixes the signal of the high band side with the signal of the low band side.
CONSTITUTION: The audio signal supplied through the input terminal 5 is supplied to the LPF8 and HPF9 having the crossover frequency of 3W7KHz by way of the AGC circuit 7 and the record amplifier 4. The output of the LPF8 is mixed with the bias current having the frequency of 50W200KHz and the current value of 300W 400μA supplied from the bias circuit 15 by way of equalizer 16, and then recorded on the magnetic tape 14 which travles in the direction of an arrow by the low-band head 12. The output of the HPF9 is mixed with the bias current having a small value of 30W100μA supplied from the bias circuit 18 by way of the limiter amplifier 10, delay circuit 11 and equalizer 17 each to be recorded on the same tape 14 through the high-band recording head 13. As a result, a high-fidelity recording/ reproduction becomes possible even in a low tape speed.
