A reproduction signal processing apparatus includes a memory circuit storing a predetermined pattern for deciding equalizing characteristics of an automatic equalizer in response to variation of a reproduction signal, a pattern converting circuit for converting the predetermined pattern outputted from the memory circuit into an equalization target pattern serving as a target of the equalization and correction by the automatic equalizer, an equalization error calculating circuit for producing an equalization error from the equalization target pattern and the equalization signal outputted from the automatic equalizer, and the automatic equalizer executing a partial response waveform process of the reproduction signal on the basis of the equalization error, for correcting the predetermined equalizing characteristics of the automatic equalizer by tracing the fluctuation of the reproduction signal. Thus, the equalization and correction tracing the variation of the equalizing characteristics of the automatic equalizer are executed, and also, the equalization and correction including the partial response waveform process are executed in the automatic equalizer.
