摘要： Where a recording medium recorded on at a slave side apparatus is reproduced, it has been made possible to perform on cite modification processing identical to that conducted at a master side apparatus, by reproducing, at the 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 an uncorrectable symbol error in one unit of a block of a specified amount of information and thus outputting the modification information corresponding to the primary information and the flag and forming, at the slave side, the parity symbol for correction of error of primary information output at the master side apparatus and recording the primary information with the 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.

摘要： This invention provides a recording and/or reproducing apparatus having a reproducing circuit for reproducing coded main information, and historical information, with respect to signal processing which was performed on the main information. An error correcting circuit corrects a code error in the main information. The reproducing circuit provides error correcting information with respect to the error correcting processing. A first constructing circuit constructs coded data based on the correcting information by concealing an error which cannot be corrected by said error correcting circuit. A decoding circuit decodes the main information provided by the first constructing circuit, and a second constructing circuit constructs decoded data by concealing the error, which cannot be corrected by the error correcting circuit, in the main data which has been decoded by the decoding circuit. The decoded data is constructed based on the historical information and the correcting information, thus preventing degradation of the signal and allowing a high quality image to be obtained.
