摘要：There is provided an information reproducing device which outputs anequalization signal P by applying equalization processing to a signal detected from astorage 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 targetwaveform generator which generates a target waveform signal T by changing at leastone level of the ideal waveform signal I, wherein erroneous decoding is reduced byoptimizing reproduction processing parameters such as the equalization coefficients CtoCor the reference levels Rto Rbased on the target waveform signal T and the informationon the storage medium is stably reproduced.
