PURPOSE:To correct the error of continuous minor loop by providing two error processing circuits and a clock distributor which supplies data to the error processing circuits, and performing independent error processing of data from adjacent minor loops. CONSTITUTION:Serial write data 352 is inputted to the 1st or 2nd error processing circuit ECC303 or ECC304, which adds an error processing code; and the data are converted by a serial converter 305 into an (m)-bit parallel write data 353 corresponding to a bubble chip and stored in an (m) units of bubble chips in parallel. On the other hand, the (m)-bit parallel read data 354 read out of the BUM301 in parallel are converted by a parallel-serial converter 306 and supplied to the ECC303 and ECC304. The ECCs 303 and 304 perform error processing independently of each other. The clock distributor 307 distributes data transfer clocks 357 from a BMCU302, (m) by (m) to the ECCs 303 and 304 as odd-numbered and even-numbered clocks 358 and 359. |
