Abstract: PROBLEM TO BE SOLVED: To speedily transfer data from a CD-ROM storage device including error correction. SOLUTION: Data read from a storage disk 50 are transmitted to both a buffer memory 66 and an error detecting circuit in parallel as a serial data stream. This error detecting method is constituted of a step for dividing the segment of the serial data stream corresponding to a data block by a polynomial for error inspection, and a step for deciding a remainder calculated by this division. When any error is not detected, data stored in the buffer memory 66 are transferred to a data bus in a host computer, and when an error is detected, error correction is continued until the remainder is reduced to zero, and the data are transferred.
