ABSTRACT:
A multi-beam optical disc system is disclosed for recording on DVD or CD optical discs. Recorded data includes inner and outer error protection codes applied to data blocks having a predetermined size. Each block comprises several sectors. Multi-channel read-out provides in parallel a set of N sub-sequences, without restriction to the block or sub-block boundaries. Sector ID codes are detected within each channel to identify a series of sub-blocks forming a part of a data block and, even in the absence of data from the start of the block, outer error protection circuitry processes the sub-blocks to accumulate a partial error protection syndrome for the block. Upon reaching the end of the block, a syndrome for a next block within the subsequence is accumulated.
