Abstract
According to one embodiment, a data decoding control apparatus includes a reading controller and a decoding controller. The reading controller reads the encoded data of a symbol unit bit by bit from a storage medium. The decoding controller computes a log-likelihood ratio (LLR) value of the symbol unit for estimate decoding calculation relative to the encoded data based on the number of bit inversion in a symbol of the encoded data and a correction factor.
