A method and an apparatus of approximately recording the sequential data of biological substances (nucleotides, amino acids, etc.) in a limited data volume. Text data showing the sequences of a column of nucleotides constituting the DNA of a standard sample E are converted into binary data in accordance with a definite conversion rule. Then the binary data are divided into partial data (A(i,j)) of m bits (m>/=16) having a plural number of rows and a plural number of columns. Next, the partial data (A(i,j)) of each row are computed in the non-sequential direction on Galois field GF (2<m>) to determine the first parity group (B1(i) to B3(i)). Then, the partial data (A(i,j)) of each column are computed in the sequential direction on Galois field GF (2<m>) to determine the second parity group (C1(j) to C3(j)). From these parity data, the sequences of the nucleotides are approximately represented.
