PURPOSE:To improve processing efficiency by executing immediately a transferring processing in case of the bit error of an ID part which can be corrected by ECC. CONSTITUTION:When the data for one sector are transferred from a disk device to a disk control device 1 are transferred, the data of the ID part (a) are applied to an ECC circuit 71 for ID, even when the bit error is detected, the data of a data part (b) corresponding to the IDa are continuously transferred as they are, and applied to an ECC circuit 72 for the data part (b). During the time, the error of the ID part (a) is analyzed, can be corrected by the correcting ability held by an ECC part 7, the data are transferred to the calculating system and the processing of the next selector can be continuously executed.
