Abstract:
A method of recording information on a recording medium by irradiating said recording medium with an energy beam, with said energy beam and said recording medium being moved relatively with each other, said recording medium being capable of being set in a first state with an energy beam at a first power level and in a second state with an energy beam at a third power level higher than said first power level, the method comprising the steps of:raising a power level of an energy beam from said first power level to a second power level higher than said first power level and lower than said third power level, and then from said second power level to said third power level, thereby changing said recording medium from said first state to said second state; and controlling a position on said recording medium, where said raising of the power level of the energy beam from the first to second power level is to be effected, depending on a time length for which said recording medium is kept in said first state before said recording medium is changed to the second state from the first state.
