摘要

PROBLEM TO BE SOLVED: To permit high density recording owing to the improvement of coding rate, to permit the superimposition of auxiliary information to main information and to perform the modulation, recording and transmission in the state which is impossible of the read-out and falsification in a simple manner by using the auxiliary information, that is, in the state which is high in security.;SOLUTION: When a continuous binary data series is transferred into an input data language of four-bit unit and, thereafter, is transferred into an output coded language string of six-bit unit which satisfies the (1, 7) RLL rule or (1, 8) RLL rule, the auxiliary information such as cipher, region, rating, identification ID, address for access, URL of related information or certified information of justified media is superimposed.;COPYRIGHT: (C)2002,JPO
