Abstract

PURPOSE: To eliminate the cross talk signal between magnetic beads placed closely each other, by performing anti-compensation through the use of the correction circuit having similar characteristics to the cross talk characteristics.
CONSTITUTION: The audio signal from the microphone is fed to the recording head 2 via the amplifiers 15 and 16 and the terminal 14, recorded on the magnetic tape, and a part of this signal is leaked to the reproducing magnetic head 1 as the cross talk. On the other hand, a part of the recording signal via the amplifier 15 is fed to the frequency characteristics correction circuit 12 via the amplifying in common use with switching, and the recording signal is formed to the characteristics similar to the cross talk signal. This signal is fed to the transistor 6 of the mixing amplifier with the phase inverted. As a result, the reproducing signal in which the cross talk due to the recording signal can be obtained from the amplifier 7.
