Abstract

PURPOSE: To make it possible to recover data error at a write time, by reading written data just after write to detect error.
CONSTITUTION: Head control circuit 12 controls read head 3 and error detection circuit 6 when data from error detection code generating circuit 5 is written onto disc 1, etc., through write head 2. Then, data written onto disc 1 at the write time is readout by head 3 just after write and is subjected to error detection by circuit 6; and if error exists, data is rewritten through an upper device according to the error detection signal which passes through bus line 10 from circuit 6, thus recovering data error at the write time. Consequently, error recovery is not impossible differently from the case where error is found at the data read time after data write time, so that the storage device can be a high-reliability device.
