    摘要: When data recording on a disk is interrupted due to the termination of data reception and recording is then resumed with reception of new data, specific data generated by a data generator (23) is added to the last block of the data received immediately before recording interruption and to the first block of the data received immediately after release of recording interruption to secure the interleave length of the aforementioned last and first blocks, respectively. Thus, the data in the last block of the received data is modulated into recording data and is recorded on the disk before recording interruption. Disk recording is resumed with recording data obtained by modulating data of the first block of the newly received data so that new recording data can be recorded so as to be continuous to the terminal end of the data already recorded on the disk without employing any link blocks.

    摘要: In an error detection method of the present invention, as shown in figure 1, 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 arranged 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: A codeword (102) for use in error correction of digital optical media, the codeword (102) having a plurality of data symbols and a plurality of parity symbols (PA1, PA2, PB3, PB4), and includes an augmented channel word (DAB) which can be read as either a first value (DA) or a second alternate value (DB). The augmented channel word is one of the plurality of data and parity symbols, wherein the augmented channel word retains its value irrespective of any error correction performed.
