ABSTRACT:
An optical disc recording method is provided for superimposing sub information by displacing edges of one or more optically-readable recording marks by a minute amount on the basis of a binary sequence code, when recording main information by forming said one or more recording marks, the optical disc recording method including a sequence generation step of generating a first binary sequence code and a second binary sequence code that is different from the first binary sequence code; a first displacement step of displacing one of the edges according to the first binary sequence code; and a second displacement step of displacing another of the edges according to the second binary sequence code.
