ABSTRACT:
An apparatus is provided for reproducing information recorded on a magnetic recording media. The recorded information is detected and amplified by a magnetic head device and a corresponding amplified detection signal is output therefrom. The amplified detection signal is input to a differentiator and to a non-ideal integrator. The outputs of the differentiator and the non-ideal integrator are subtracted from each other and the thus subtracted signal is applied to a zero crossing point detector. Pulses are generated representing the recorded information at each zero crossing point deteted by the zero crossing point detector. Since the non-ideal integrator does not effect integration of DC and low frequency signals, a compensating device is provided for generating a corresponding DC and low frequency signal and for adding this signal to the output signal of the non-ideal integrator.
