ABSTRACT:
When sequential records are sequentially written to data blocks each having a fixed length on a disc storage medium, data to be saved are stored in a buffer of a main memory in addition to previously accumulated saved data, and a first data block A and a second data block C which is located apart from the first data block A at a distance of at least one block size, are updated alternately by moving all data, including the data to be saved and the previously accumulated saved data, stored in the buffer, to the data block. This method enables sequential records to be added and written while insuring the integrity of the data without lowering the data transfer efficiency.
