Abstract

PURPOSE: To make it possible to acknowledge a storage address lost and also to detect automatically the error of read data, by adding a label to each data block at a constant position.
CONSTITUTION: In a data storage unit, when write circuit 3 writes data blocks 6 into file memory 2 in sequence, data discrimination signal 9 is fixed to 100 and added to the tinitial part of each block 6 and block discrimination number 10 is given a number increasing by one according to blocks, so that each block 6 will be stored in memory 2 being given label 8 at its initial part in inside 7 through write operation. At the time of a read, on the other hand, read circuit 4 reads sequentially data blocks from memory 2 according to the instruction of control part 1, but circuit 4 refers to the contents of label 8 to make sure by collating that signal 9 is 100 and number 10 increases sequentially by one from 30. As a result, the error of read data can automatically be detected and the influence of the error can be prevented.
