Abstract

An information recording method for recording information by forming record marks in a data region of a recording medium such that the information corresponds to both ends of each of the record marks. First and second adjustment or guard regions are provided before and after the data region. The lengths of the first and second adjustment regions are changed with the start position of the first adjustment region being changed such that the position of the data region is shifted. In addition, when the same information is recorded a plurality of times, an array of record marks recorded on the recording medium in association with the information includes an array in which the record marks and the spaces between the marks are reversed each other in their positions.
