ABSTRACT:
It is an object of the present invention to provide an information recording method for recording information in a data rewritable type optical recording medium having a plurality of information recording layers, which can form recording marks having good shapes. In the information recording method according to the present invention, a plurality of recording marks selected from a group consisting of several types of recording marks with different lengths each corresponding to an integral multiple of a clock cycle T are formed in an optical recording medium10having at least a stacked L0 layer20and L1 layer30by projecting a laser beam thereonto via a light incidence plane13aand the number of pulses of the laser beam to be projected onto the L0 layer20when at least one type of the recording mark among the several types of recording marks is formed therein is set to be smaller than the number of pulses of the laser beam to be projected onto the L1 layer30when the at least one type of the recording mark is formed therein.
