ABSTRACT:
An ECC decoder outputs, to a likelihood substituting unit, information on data in data blocks that is corrected to be valid. Based on the information, the likelihood substituting unit substitutes likelihood corresponding to the data corrected to be valid by the maximum value, and outputs it to an LDPC decoder. The LDPC decoder decodes user data with likelihoods partly substituted by the maximum value using LDPC parity, and calculates likelihood of data that constitutes the user data. The LDPC decoder outputs the calculated likelihood to a channel APP decoder as external data.
