摘要： In an error detection method of the present invention, target code strings which are inputted in a discontinuous arrangement are subjected to a syndrome operation, and simultaneously, the target code strings which are inputted in a discontinuous arrangement are subjected to a first error detection code operation while correcting the inter-data continuity by skipping the data so that the arrangement of the code strings have continuity. Then, error data positions and error data numerical values of the target code strings are calculated on the basis of a syndrome obtained in the syndrome operation, and only the error data position among the target code strings are subjected to a second error detection code operation again on the basis of the error data positions and the error data numerical values. Using the operation result, the operation result by the first error detection code operation is updated, thereby simultaneously performing ECC processing and EDC processing for the target code strings which are inputted in a discontinuous arrangement.

摘要： In an error correction method for performing error correction on an error correction unit block in which main data are interleaved, after rearranging code lines in the order of error correction, it is judged whether the corresponding erasure position information indicates “erasure of data” or not with respect to only byte positions in a code line at a boundary between a main data area and a sub data area or a SY area, and erasure position information is set for only positions where erasure position information should be newly obtained. With respect to other byte positions, erasure position information at the same byte positions in a previous code line in the error correction order is set. However, when the previous code line is an error-incorrectable code line, erasure position information is set for all byte positions in a code line that is next to the incorrectable code line in the error correction order. With respect to the subsequent code lines, erasure position information is set until the target byte position reaches the next boundary between the main data area and the sub data area or the SY area. Thereby, the time required for error correction can be reduced.
摘要翻译：在对主数据进行交错的纠错单元块进行纠错的纠错方法中，在按照纠错的顺序重排代码行之后，判断相应的擦除位置信息是否表示“数据的擦除” 相对于主数据区域和子数据区域或SY区域之间的边界处的代码行中的仅字节位置，并且擦除位置信息仅设置为应当新获得擦除位置信息的位置。关于其他字节位置，设置纠错顺序中的先前代码行中相同字节位置处的擦除位置信息。然而，当前一代码行是错误不正确的代码行时，在错误校正顺序中的错误代码行旁边的代码行中为所有字节位置设置擦除位置信息。对于后续的代码行，设置擦除位置信息，直到目标字节位置到达主数据区域和子数据区域或SY区域之间的下一个边界。从而可以减少误差校正所需的时间。
