摘要：In a data reproduction method and apparatus of the present invention, a Viterbidetection unit is provided, the Viterbi detection unit having a plurality of detectors eachproviding a first partial response signal with a first constraint length from a first sequenceof samples derived from a first readout signal. One of connection and disconnection ofthe plurality of detectors in the Viterbi detection unit is selected in response to a timingsignal, wherein, when the connection of the plurality of detectors is selected, the Viterbidetection unit provides a second partial response signal with a second constraint lengthfrom a second sequence of samples derived from a second readout signal, the secondconstraint length being different from the first constraint length.
