Recorded information reproducing apparatus

摘要

A recorded information reproducing apparatus is capable of highly reliably reproducing information even from a recording medium on which recorded information including recorded signals in a low frequency band are recorded at a high density. An error voltage is subtracted from an analog read signal read from a recording medium to generate a corrected read signal. The corrected read signal is sampled to be converted into a digital corrected read sample sequence from which recorded information is decoded. Here, the sample existing at a position nearest to each zero-cross point in the corrected read sample sequence is extracted from the corrected read sample sequence to generate an extracted sample sequence. Each sample in the extracted sample sequence is converted into an analog signal having a level corresponding to the associated sample value. This analog signal is used as the above error voltage.
