Abstract

PURPOSE: To enable excellent recording even with slower tape running speed, by shifting either one of the phases of the output signal of the third power circuit and the recording signal to another, and feeding those signals to the magnetic head after superposition.
CONSTITUTION: The recording signal from the input terminal 11 is fed to the phase delay circuit 13 via the recording equalizer circuit 12, a part of the signal is third- powered in the third power circuit 14. The third-powered signal and the signal from the phase delay circuit 13 are superimposed and fed to the adder 15, where AC bias signal is superimposed, and the superimposed signal is fed to the recording magnetic head 16. Thus, the recorded phase of each signal recorded as residual magnetization on the magnetic recording media is in agreement. Even with lower tape running speed, the operation compensating the distortion of third harmonics through the use of the third power circuit can not be defected to establish excellent magnetic recording and reproduction.
