Abstract: An optical disk is provided to include one data recording layer, and to dispose lead-in zones, data zones, and lead-out zones at the recording layer, thereby more reliably recording more control data. The first control data zone is disposed in a lead-in zone of a recording layer, while the second control data zone is disposed in a lead-out zone of the recording layer. Control data for using an optical disk are repeatedly recorded in the first control data zone and the second control data zone. The same control data are repeatedly recorded in either the first control data zone or the second control data zone. The control data are recorded in the control data zones by using bi-phase modulated wobble signals.

Abstract: PURPOSE: A device and a method for coding error correction are provided to satisfy a property needed for a parity check matrix by moving a position of components generating a cycle among the components of the generated parity check matrix, and enhance an LDPC(Low Density Parity Code) decoding performance by generating the parity check matrix removing the cycle. CONSTITUTION: A parity check matrix generator(110) generates the parity check matrix respectively including the components having an 1-component value for each row and column, and other components having a 0-component value. A parity check matrix adjuster(130) searches a cycle forming group from the parity check matrix by receiving the parity check matrix from the parity check matrix generator. If the cycle forming group is existed more than one, the parity check matrix adjuster outputs the parity check matrix that the cycle forming group is removed by replacing the 1-component value with the 0-component value of the cycle forming group. An LDPC coder(150) performs the LDPC coding by receiving the parity check matrix that the cycle forming group is removed and a message word.
