摘要：
The invention provides information recording apparatus, information reproducing apparatus, and information recording medium, capable of correcting an error due to the change in RF signal level caused by noise or the like without a significant reduction in the storage capacity. An edge modulating circuit generates a signal corresponding to digital information consisting of units each consisting of a predetermined plurality of bits. Pits are formed on in information recording medium in such a manner that the edge positions of the pits are shifted in a discrete fashion according to the signal output from the edge modulating circuit. An error correcting circuit generates an error correction code. The resultant error correction code is added at part of bits of the predetermined plurality of bits.
