摘要： A recording medium in which information is to be recorded is permitted to get into a first state by a first power level of an energy beam and permitted to get into a second state by a second power level higher than the first power level of the energy beam. The information is recorded on the recording medium by moving the energy beam and the recording medium relatively to each other and irradiating the recording medium with the energy beam so that the first and second states are formed with predetermined lengths and at predetermined intervals on the recording medium. Four power levels (first, second, third and fourth power levels) are used as the power level of the energy beam. The information is recorded while the second power level is increased to x times and the first, third and fourth power levels are increased to y times. The information recorded as described above is reproduced, and reproductive jitter is observed. The magnification factors x and y are adjusted so that the value of the reproductive jitter is not larger than a predetermined value.

摘要： 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.
