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.

Abstract: A reproducing device performs decoding by propagating the reliability, and detects micro medium defects to correct the reliability information. The decoder has an internal decoder, external decoder and a defect detector which calculates a moving average value of a soft-input signal, acquires a scaling factor from this, and manipulates the reliability information of the internal decoder. Since micro-defects can be detected accurately and the reliability information of the internal decoder is manipulated, error propagation due to micro defects can be suppressed.

Abstract: A decoder decodes a code by selecting, based on a predetermined condition, a path out of paths representing a transition of each of states in a trellis diagram. A storing unit stores, when a path at time k is selected, information on a selection history of a path selected at time prior to time (k?(a constraint length of a code)+1). A path detecting unit detects a path to be excluded from a path selection candidate, based on the information stored in the storing unit and information on a state of a transition source when a state transition occurs from time k?1 to time k.
