PURPOSE:To detect an error at the time of writing a data by keeping pace with the time when writing a data, by using for a detection a data by a magnetic bubble which is left without being transferred to a minor loop, in a write major line. CONSTITUTION:A minor loop is divided into an even loop 21 and an odd loop 22, each of them is arranged at an interval of 2-bit, and the even number-th bit of a write major line 25 and the odd number-th bit of a write major line 26 are transferred to the even loop and the odd loop, respectively. Accordingly, a magnetic bubble written in the odd number-th bit of the major line 25 and the even number-th bit of the major line 26 is transferred to an end part 31 or 32 of the major line by a rotating magnetic field, and detected by a detector 41 and 42, respectively. Information detected by the detector 41 is equal to information stored in the odd loop, information detected by the detector 42 is equal to information stored in the even loop, outputs of 41 and 42 are collated with a write designated data from a CNT by a collating circuit 43, and an error is detected. |
