Optical recording method and optical recording device

An optical recording method of recording information on an optical recording medium having a recording thin film on a substrate, the state of the recording thin film being changed by irradiating optical beams,

• wherein in order to record the information on the recording thin film as lengths of marks and spaces, when irradiating optical beams on the recording thin film, the power of the optical beams being modulated in the pulse train including a starting-end, an intermediate portion, and an end according to the lengths of the marks and spaces, the power of an optical beam irradiated to the starting-end is changed according to the lengths of a mark to be recorded, of a space directly in front of the mark, and of a mark in front of the space.
