ABSTRACT:
A data reproduction apparatus for adjusting filter coefficients of an equalizer including a digital filter, and connected before a Viterbi detector and a method therefor. A level of the output value of the equalizer is detected based on a reference level set in the Viterbi detector, and a level error of the detected level with respect to a predetermined reference value is detected. The filter coefficients of the equalizer are adjusted such that the level error is minimized, thereby improving the detection performance of the Viterbi detector.
