Abstract
PURPOSE:To reproduce digital signal of high quality, by making excellent crosstalk compensation reardless of level variance between tracks at all times, through the formation of crosstalk compensating signal, after the level compensation of reproducing output signal. CONSTITUTION:The reproducing signal from a head 1 is amplified 2, and then fed to an automatic gain control circuit 3 to keep the reproducing output signal level. Thus, the level difference between tracks can be compensated. After this signal of a given level is in phase inversion 4, it is given to attenuators 5a, 5b in which the attenuation coefficient is in coincidence with the crosstalk coefficient. Further, the output of the circuit 4 corresponding to N-th-track and the output of the attenuators 5b', 5a'' corresponding to N-1 and N+1-th tracks are added 6. Thus, the reproducing output signal in N-tracks without crosstalk can be obtained.
