PURPOSE:To record the changing information of plural quantities of data differing in change frequencies more, by providing an auxiliary recording part and providing a main recording part which transcribes the data in the auxiliary recording part when the storage capacity thereof is filled by the data. CONSTITUTION:Sampling clock signals are inputted to a control circuit 12 for recording time and a control circuit 14 for data recording by a setting circuit 15 and a generating circuit 14 for sampling clocks, and the trigger signals from a trigger generating circuit 10 corresponding to the set conditions of a trigger setting circuit 11 are inputted through the circuit 12 to a data recording circuit 16, by which the other data D2-D4 together with the data D1 are recorded succesively at the fine sampling clock frequencies which change very rarely in auxiliary memories 1-4. When the memories are filled with the data to their full capacity, the data is transferred to main memories 5-8 by the signals from a control circuit 16 and an address control circuit 17. Thus the recording of the information differing in change frequencies is increased. |
