Patent ID: 7590929

Claim:
A record reproduction apparatus that uses an error correcting code and an iterative method, comprising: an encoding unit that divides sector data to be written into a recording medium into plural blocks and encodes each of the blocks using an LDPC code; an iterative decoding unit that divides data read from the recording medium into the plural blocks and iteratively decodes each of the blocks divided from the read data using an LDPC decoder; and an error correcting unit that corrects, after the iterative decoding unit iteratively decodes the sector data, an error based on a predetermined length of parity symbols, the predetermined length of parity symbols being equivalent to two times as many as a number of correctable symbol errors, wherein the predetermined length of parity symbols is determined so that a total error correction capability with the LDPC code is equal or more than a total error correction capability in the case that the sector data is not divided before encoded using the LDPC code.
