    Abstract: Described herewith is an optical disk manufacturing apparatus for reading recorded digital data from an optical disk, comprising an encryption unit (22, 23) for encrypting entered digital data according to a plurality of key information; an optical disk substrate manufacturing unit 2 for manufacturing an optical disk substrate 4 on which the encrypted digital data and key information are recorded in the form of physical form changes; a reflection film forming unit 41 for forming a reflection film on the optical disk substrate 4; and a key information recording unit 7 for recording key information on the optical disk substrate on which the reflection film is formed. The reflection factor of the optical disk is changed locally, thereby giving a jitter to the position information of each pit edge, and desired data is recorded additionally according to this jitter. Pits, etc. are disposed so as to be deviated from the track center towards the inner/outer region of the optical disk 2, thereby recording such sub-data as key information KY, etc.

    Abstract: The present invention relates to an information recording apparatus, an information recording method, an information recording medium, an information reproducing apparatus and an information reproducing method by which in the case in which the present invention is applied to an optical disk system by, for example, a compact disk or the like and data or the like related to copyright is recorded by partial change of a pit shape or the like, the data can be reproduced with certainty without repeatedly recording the data. According to the present invention, with regard to a defect having a size by which at least main data can be reproduced correctly, 1 bit of sub-data SB is allocated to a pit row or the like having a predetermined length or more such that the sub-data SB can be reproduced correctly.
