    Abstract: A method and apparatus to reproduce and/or record data from and/or to an optical recording medium. The method includes detecting a wobble signal from the optical recording medium, predicting a wobble channel state from the detected wobble signal, detecting an information signal from the optical recording medium, predicting an information channel state from the detected information signal. If a damaged section is discovered from the optical recording medium, the information signal is decoded based on the information on the wobble channel state or the information on the information channel state. Accordingly, data can be reproduced more effectively by predicting a channel state of an information (RF) signal and a channel state of a wobble signal.

The method comprises: generating code word vectors by generating column parity information using a parity check matrix and message information; selecting code word bits for generating row parity information among code word bits in the generated code word vectors; and generating the row parity information using the selected code word bits, wherein the selecting of the code word bits comprises: excluding code word bits related to the generation of other row parity information.

    Abstract: The present invention relates to an error correction method and apparatus for determining whether an error exists in a decoded binary signal and correcting the error if the error exists in a decoding apparatus using a low density parity check (LDPC). The method comprises: generating a resultant matrix (m*1) by performing an XOR operation and a modular 2 operation with respect to an LDPC matrix (m*n) and a code word vector (n*1); determining whether a decoding of the code word vector succeeded on the basis of the resultant matrix; and if it is determined that the decoding failed, detecting a code word bit, in which an error is generated, in the code word vector on the basis of correlations of components of the LDPC matrix, code word vector, and resultant matrix. Accordingly, the decoding apparatus using the LDPC can prevent a small number of errors from causing a total block to be determined as a decoding failure and correct an error when it is determined that only one bit error exists.
