A method and apparatus for reproducing data, by which the quality of signals input to a Viterbi decoder are improved by using a two-step equalizer, and the Viterbi decoder is operated in an optimum state so that the quality of reproduction signals is improved, the apparatus including: a first equalizing unit to compensate for frequency gain properties of an input signal according to predetermined levels, a second equalizing unit to reduce noise of the input signal processed by the first equalizing unit, and a Viterbi decoder to Viterbi-decode the input signal processed by the second equalizing unit to output a binary signal corresponding to the data.
