ABSTRACT:
A reproducing apparatus includes a signal reading unit for reading a signal from a recording medium, an equalizing unit for performing partial response equalization on the read signal and outputting an equalized signal, a maximum likelihood decoding unit for performing maximum likelihood decoding on the equalized signal to decode binary data and outputting a binary data string, a determining unit for determining whether or not a shortest code in the binary data string obtained by the maximum likelihood decoding is correct, on the basis of information on an amplitude of the equalized signal corresponding to the shortest code, a code correcting unit for correcting the shortest code in the binary data string, in accordance with a result of the determination of the determination unit, and a data demodulating unit for demodulating the binary data string obtained through the code correcting unit to obtain reproduction data from the recording medium.
