PURPOSE:To execute an automatic release when an address check circuit detects an error by executing autonomously when one system is at fault of address mismatching, and also executing autonomously the transfer of a data from a normal system. CONSTITUTION:When an address checking circuit 33 in a magnetic bubble control part 3 detects an error and returns a signal to a device selection controlling circuit 5, an error processing circuit 52 sends a signal to a data switching circuit 51, and supplies an instruction so that it is switched to a data line of the side B from a data line of the side A. In such a way, the connection is switched to the normal B side device from the faulty A side device. Also, the error processing circuit 52 starts an initializing circuit 34 of the faulty device, erases information of a magnetic bubble storage part 1, and simultaneously, initialize the inside of the magnetic bubble controlling circuit 3. Thereafter, address information is written in the magnetic bubble storage part 1, a data of a magnetic bubble storage part 2 of the side B is transferred through the data switching circuit 51, the same contents are copied, the device goes to a standby state, and the recovering is completed. |
