SO 1328 ABSTRACT A method of reducing DC components in a digital information signal comprised of a plurality of 8-bit data words by converting each of the 8-bit data words to a 10-bit data word, comprises the steps of grouping the 10- bit data words by weight in accordance with the run length of data of each of the, 10-bit data words, with the 10-bit data words only including five or six logic level "1" bits; assigning each of the 8-bit data words to one of the 10-bit data words in accordance with the frequency of occurrence of the 8-bit data words so that 8-bit data words having a high frequency of occurrence are assigned to 10-bit data words having a short run length; classifying the grouped 10-bit data words into a first group consisting of 10-bit data words having five logic level "1" bits, a second group consisting of 10-bit data words having six logic level "1" bits, and a third group consisting of 10-bit data words having four logic level "1" bits, with the third group being formed by inverting the 10-bit words in the second group; and further assigning the 8-bit words alternately to the 10-bit words in the second and third groups when such 8-bit words correspond to previously- assigned 10-bit words having six logic level "1" bits and assigning the remaining 8-bit words to the 10-bit words in the first group. -1-
