    摘要： An error correction method for optical discs, and more particularly, an error correction method appropriate to high density discs is provided. The error correction method adds inner parity and outer parity to an error correction block of size n byte x m x o. The method comprises the steps of obtaining a plurality of inner parity blocks (PI blocks) by segmenting the error correction block in the inner parity (PI) direction into x segments; generating e-byte PI for each of the plurality of PI blocks generated by segmenting, and adding e-bytes PIs to the PI blocks in the PI direction; and generating f-byte outer parity (PO) in the PO direction of the error correction block, and adding the POs to the PO direction. The error correction method enhances error correction capability while maintaining a redundancy of parity signal on a level similar to conventional DVDs.

    摘要： In a data demodulating method and apparatus, and a code arranging method, a multiplexer multiplexes an input data stream divided by a predetermined length into a plurality of types of pseudo random data streams using multiplexed information of predetermined bits by applying a predetermined multiplexing method to each of the pseudo random data streams. An encoder RLL-modulates the plurality of types of pseudo random data streams to create a modulated code stream including a minimum of DC components. The multiplexer generates the random data streams by inconsecutively scrambling the input data stream using the multiplexed information. The encoder weak DC-free RLL-modulates each of the multiplexed data streams without using a DC control sub code conversion table to which additional bits are added and provides a code stream including a minimum of DC components among multiplexed, RLL-modulated code streams.

    摘要： A BCA (Burst Cutting Area) code including a unique disk code indicating the type of a disk is written in a BCA code area of the disk. If the disk is mounted into the optical disk player, the optical disk player reads data written in the BCA code area, extracts the disk code contained in the read data, and confirms the type of the disk corresponding to the extracted disk code by retrieving a disk code table in which disk codes corresponding to the types of disks are mapped.

    摘要： A method for generating a land/groove (L/G) switching signal from pits on a land/groove (POLG) type disc and an apparatus therefor. In the method for generating an L/G switching signal from pits on a POLG type disc having tracks with wobbles, in which header information is recorded in sectors of each track, the header information including physical identification data (PID) and a peak header and a bottom header distinguished by envelopes of the peak header signal and the bottom header signal and both the peak and bottom header signals having phases according to lands or grooves, the phases of the peak header signal and the bottom header signal are compared to determine a track switching point and the sequence of sectors is determined using the physical identification data of the disc. Then, the number of sectors included in each track is counted based on the number of wobble signal cycles reproduced from the disc, to determine a track switching point and a land/groove (L/G) switching signal is generated corresponding to the results of these steps. Therefore, a L/G switching point is accurately determined using the continuity of the PID and the number of wobbles signal cycles so that precise tracking control can be achieved.
