Abstract
The present invention relates to a method of correcting data on a high-density recording medium such as a BD-ROM (Blu-ray ROM Disk) and a BD-RW (Blu-ray ReWritable Disk). In the present method, whether there is any error in a predetermined-sized LDC data block, which is included in a physical cluster, is determined based on if there is an error in sync data and BIS data neighboring the LDC data block, and, if determined to be erroneous, error correcting operation for the LDC block is conducted.
Claims5
A method of correcting errors in data recorded on a high-density recording medium, comprising the steps of:
- (a) determining whether an error exists in a long distance code block of a predefined size contained in a physical cluster being reproduced from the high-density recording medium based on whether errors exist in burst indicating sub-code data and sync data adjacent to the long distance code block;
- and
- (b) selectively performing an error correction operation for said long distance code block depending on the determination result.
