ABSTRACT OF THE DISCLOSURE A signal processing circuit for converting analog sig- nals of regenerated data from a recording medium, including a header for the following data, into pulse signals, which samples amplitude of the regenerated signals at the header, judges whether the sampled amplitudes are within a pre- scribed range or not, and only when the sampled amplitudes being judged to be within a prescribed range, gives a con- trol signal to an amplifier to amplify the amplitudes of the regenerated signals by such a gain as to make a peak-to-peak amplitude of the sampled amplitudes at the header be a fixed value.
