Abstract
A data storage controlling device including: a data dividing section for dividing target data made by a set of elements, each element being expressed in multiple values, into groups of partial data made by a set of elements, each element being expressed in two values, or dividing target data made by a set of elements, each element being expressed in two values, to partial data made by a subset of the elements; a compression section for generating compressed data blocks by means of reversibly compressing the partial data and of dividing the compressed data into predetermined size of blocks; an identifier assigning section for assigning an identifier for identifying partial data from which the compressed data block is generated to each compressed data block; and a storage processing section for reserving a storage area being smaller than the size of the target data and being common to the partial data and storing the generated compressed data block into the storage area.
