Abstract

PURPOSE:To improve the high band frequency characteristics, by recording the high and low band of voice signal on each track with optimum bias, and synthesizing the output signal of both the tracks at reproduction. CONSTITUTION:After the input signal fed to the input terminal 12 is amplified at the recording amplifier 13, it is fed to the low-pass filter 13 and high-pass filter 14, and the low and medium tone signal of the low-pass filter is amplified at the low recording compensation circuit 16 and recording drive circuit 22', and the AC bias suitable for low tone fed via the capacitor 21 is recorded on the medium and low tone band recording track with the recording head 18. On the other hand, the high band signal output from the high-pass filter 15 is similarly amplified at the high band recording compensation circuit 17 and the recording drive circuit 22 and recorded on the high band recording track with the recording head 18 through the AC bias suitable for the high band signal. The signal with high fidelity can be reproduced by mixing the signal recorded on the magnetic tape.
