发明名称
摘要 This invention relates to an optical recording method and apparatus, in which the intensity of a laser beam to be radiated onto an optical recording medium is raised from an intensity Ppre for maintaining a pre-heat state in which the temperature of the medium surface becomes a predetermined temperature, to PW1 higher than Ppre, the intensity is reduced to an intensity PLT lower than PW1 after PW1 is maintained for a time TW1, and thereafter, the laser beam is intensity-modulated between PLT and an intensity PW2 higher than PLT so as to form a mark on the optical recording medium. When at least one of PW2, PLT, and a time TW2 for maintaining PW2 is controlled, the medium temperature, after an elapse of TW1, at the peak temperature position or the spot center position of the laser beam radiated onto the medium surface is equal to the medium temperature after an elapse of TW2.
