Patent ID: 7301870

Claim:
An information recording method for recording information by irradiating an optical beam from a luminous source to a recording medium, and forming recording marks, said optical beam being modulated by recording information, comprising: a first trial writing step for writing first predetermined test data on a trial writing area of said recording medium, wherein recording power of said optical beam is gradually changed, and for determining a first optimum recording power level based on a reproduction signal of said first predetermined test data; a second trial writing step for writing second predetermined test data on said trial writing area of said recording medium, wherein recording power of said optical beam for recording a specific pattern is gradually changed while said recording power for patterns other than said specific pattern is set at said first optimum recording power level, and for determining a second optimum recording power level, which is the optimum recording power level for said specific pattern, based on a reproduction signal of said second predetermined test data; and a step of writing said recording information at said second optimum recording power level for said specific pattern and at said first optimum recording power level for patterns other than said specific pattern.
