PURPOSE:To remarkably enhance processing capacity when correctable reading error is occurred by providing plural data processing routes and switching input data and output data in these data processing routes respectively. CONSTITUTION:An input data switching means 21 switches output path of input data from memory unit 1 and outputs data to reading error information preparing means 22, 25 respectively. Reading error information preparing means 22, 25 prepare the reading error information of input data and sends out the reading error information to reading error correcting means 24, 27 and at the same time, sends out input data to data storing means 23, 27 respectively to store them. Reading error correcting means 24, 27 correct output data from data storing means 23, 26 by these reading error information, and send out them to an output data switching means 28. The output data switching means 28 switches output the data of reading error correcting means 24, 27 and sends out the data to a host processor 3. |
