ABSTRACT:
It is an object of the present invention to provide a method for recording data in an optical recording medium which can form a recording mark having desired length and width in a write-once type optical recording medium. The method for recording data in an optical recording medium according to the present invention is constituted so as to project a laser beam whose power is modulated by a pulse train pattern onto an optical recording medium including a substrate, a first recording layer, a second recording layer and a light transmission layer16wherein a recording pulse of the pulse train pattern is divided into (n−1) divided pulses and the power of the laser beam is set to a recording power Pw at the peak of each of the divided pulses, set to a second bottom power Pb2at a portion immediately after a last divided pulse and set to a first bottom power Pb1at other intervals where Pb1is higher than Pb2.
