PURPOSE:To avoid such a case where the wrong data are stored in a storage means by inhibiting the restoring of data when a saving action is interrupted owing to the generation of a fault and others. CONSTITUTION:A data storage control circuit 3 resets a data saving instruction part 5 before the data stored in a memory 2 is saved to a magnetic disk device 4 and then saves the data. Then the circuit 3 sets the part 5 when the saving of data is through in a correct way. In case some fault occurs while data are saved and the data saving action is interrupted, the part 5 is kept reset as it is. Then the circuit 3 checks the part 5 when the data saved to the device 4 are stored again in the memory 2 and stores the data again as long as the part 5 is set. While these data are not stored again if they are reset. |
