PURPOSE:To improve the data processing speed and the safety of data by writing the dame data into a memory and a disk. CONSTITUTION:The data are written into a memory 4 and a disk 5, and the data are read out of the memory 4 for the purpose of reference. Thus the data processing speed is improved. For instance, the data are written into and read out of the memory 4 via the paths 101 - 103. In other words, the data are obtained by means of the memory 4 and without using the disk 5 and the data processing time can be extremely shortened. Meanwhile the safety of data is not completely assured with the recording carried out through the memory 4 only. Therefore the data are written in the disk 5 with another disk writing task 3. Thus the safety of data is improved when the same data are written into the memory 4 and the disk 5 in regard of the recording of data. |
