摘要：
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 are formed in an optical recording medium 10 having at least a stacked L0 layer 20 and L1 layer 30 by projecting a laser beam via a light incidence plane. In the case of forming at least one recording mark among the several types of recording marks in L0 layer 20, the recording powers of a top pulse Ttop and a last pulse Tlp of the laser beam are set to Pw0′ lower than the recording power Pw0 of a multi-pulse Tmp thereof.
