A magnetic recording and reproducing apparatus includes an equalization section for equalizing a signal sequence which is reproduced from a magnetic recording medium and outputting an equalized waveform, and {HEAD ~ a conversion section} for converting {TAIL ~ the equalized waveform} into a maximum likelihood sequence by carrying out metric calculation based on average values of the equalized waveform
