Abstract: A magnetic recording and reproduction apparatus, includes a circuit for changing a reference amplitude value of a Viterbi detector. The circuit is used to record and reproduce data with the reference amplitude value displaced from a reference value, thereby measuring the data error rate. Displacement of the reference amplitude from a reference value increases the data error rate, and therefore the data error rate can be measured within a short time. A data error rate with the reference amplitude equal to a reference value is estimated from the data error rate measurement, thereby making it possible to evaluate the degree of accuracy of a magnetic recording and reproduction apparatus. The data error rate is measured with the reference amplitude of the Viterbi detector displaced from a reference value while changing the equalization coefficient value of a waveform equalizer, the cut-off frequency of a low-pass filter and the write precompensation amount of a write precompensation circuit. In this way, the effect of the reproduction channel parameter or the write precompensation amount on the degree of accuracy of the magnetic recording and reproduction apparatus is evaluated, and the optimum value of the reproduction channel parameter or the write precompensation amount can thus be determined.

Abstract: A nonlinear compensation A/D converting method and a circuit for compensating asymmetry of a reproduction signal waveform, so as not to deteriorate the performance of a discriminator even if there is a nonlinearity such that the amplitudes of the signal differ in dependence on the polarities of the waveforms like a reproduction waveform of an MR head are provided. Scales 1+ and 1- of an A/D converter are set to values which differ in dependence on the positive and negative polarities of the input signal, so that a nonlinear compensation which is suitable for a high accurate and high speed operation can be realized. Even an MR head in which the asymmetry between the upper and lower waveforms of the reproduction waveform is large can be used. A yield of the head can be improved.
