A method for recording data in an optical recording medium according to present
invention is constituted so that data are recorded in an optical recording medium
including a light transmission layer and two recording layers by projecting a laser
beam whose power is pulse-like modulated between a recording power and a bottom
power lower than the recording power onto the optical recording medium from a side
of the light transmission layer and forming recording marks having different lengths
in the recording layers and that when a recording mark having a longer length than
that of the shortest recording mark is to be formed in the recording layers by
modulating the power of a laser beam using a single pulse, a time of raising the
power of the laser beam to the recording power is delayed relative to a time of
raising the power of the laser beam to the recording power when the shortest recording
mark is to be formed. In the case of recording data in the optical recording medium
in accordance with the thus constituted method for recording data in an optical
recording medium, jitter of a reproduced signal obtained by reproducing the recorded
data can be markedly reduced.
