Abstract
To record data, pieces of second data are produced by dividing supplied first data and an error correction code is added, and the pieces of second data and the error correction code are allocated to and recorded in a plurality of recording and reproducing units, respectively. To reproduce data, the first data is reproduced by synthesizing the pieces of second data read from the plurality of recording and reproducing units. If a fault occurs at any one of the plurality of recording and reproducing units, and if the faulty unit has recorded one of the second pieces of data, the first data is reproduced by reading the second pieces of data and error correction code recorded in the plurality of faultless recording and reproducing units, and if the faulty unit has not recorded one of the pieces of second data, the first data is reproduced by reading the pieces of second data recorded in the plurality of faultless recording and reproducing units. New pieces of second data are produced by diving the reproduced first data and a new error correction code is added, and the new pieces of second data and the new error correction code are allocated to and recorded in the plurality of faultless recording and reproducing units.
