Abstract
There is provided an information reproducing device which outputs an equalization signal P by applying equalization processing to a signal detected from a storage medium based on equalization coefficients Cto C, outputs a decoding signal d by applying maximum likelihood decoding processing based on reference levels Rto R, generates an ideal waveform signal I based on the equalization signal, and has a target waveform generator which generates a target waveform signal T by changing at least one level of the ideal waveform signal I, wherein erroneous decoding is reduced by optimizing reproduction processing parameters such as the equalization coefficients Cto Cor the reference levels Rto Rbased on the target waveform signal T and the information on the storage medium is stably reproduced.
