Abstract
A recording/reproduction device includes a reading mechanism to read information data stored in a floppy disk and constituted by a plurality of byte data and first inspection data and second inspection data to detect an error of the information data. First and second calculation mechanism calculate a first and second syndrome value from the byte data and the first and second inspection data, respectively. First and second error correction mechanisms perform error correction for the information data on the basis of the first and second syndrome value, respectively. A computer includes the second error correction mechanism. Because the second error correction is not performed in the floppy disk drive, the capacity of a storage unit is decreased, a memory in the floppy disk drive can be considerably smaller than that of a conventional floppy disk drive, and the cost of the floppy disk drive can be reduced. In addition, since secondary correction is not performed in the floppy disk drive, an increase in data transfer rate from the floppy disk drive to the computer can be realized.
