摘要

For the cases where recording medium recorded at slave side apparatus is reproduced it has been made possible to do identical modification processing to that conducted at master side apparatus, by reproducing, at master side apparatus, the primary information added with parity symbol for error correction from the recording medium on which the primary information is recorded, correcting the symbol error of primary information reproduced at the reproducing means using the reproduced parity symbol, producing the flag which indicates the production of uncorrectable symbol error in one unit of the block of specified information amount and thus outputting the modification information corresponding to the primary information and the flag and forming, at slave side, the parity symbol for correction of error of primary information output at the master side apparatus and recording the primary information added with parity symbol and modification information on the same recording medium. It has also become possible to conduct satisfactory modification processing when the symbol error is produced.
