A decoder device includes: a decoder that decodes data stored in a storage medium by performing error correction on the data, the error correction being capable of correcting code error and code erasure included in the data; a memory that stores a history of an address in the storage medium of a code included in the data, the code being detected to have the code error by the decoding unit; and a controller that controls the decoder to change a detail of the error correction based on the history stored in the memory.
