DATA PROCESSING METHOD FOR GENERATING ERROR CORRECTION PRODUCT CODE BLOCK, DATA PROCESSING METHOD FOR RECORDING DATA IN RECORDING MEDIUM, AND DATA PROCESSING DEVICE FOR DATA

摘要

In line with progress in semiconductors and recording and transmission technologies, an error correcting capacity is enhanced by enlarging a size of an entire Reed Solomon error correction product code block with a redundancy rate kept constant. Unlike the way a Reed Solomon error correction product code block of (M + PO) x (N + PI) byte is conventionally constituted for information data of (M x N) byte, a Reed Solomon error correction product code block of (K x (M + 1) x (N + P)) bytes is constituted (A, B, C) for information data of (K x M x N) bytes so that K is made variable to make a size of an entire Reed Solomon error correction product code block variable, thereby enabling changing of an error correcting capacity substantially in proportion to K without increasing the redundancy rate.
