Abstract:
1. A method for recording data in an optical recording medium wherein data are recorded in an optical recording medium including a light transmission layer and at least one recording layer by projecting a laser beam whose power is pulse-like modulated between at least 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, which method for recording data in an optical recording medium is constituted so that when a recording mark having a longer length than that of the shortest recording mark is to be formed in the at least one recording layer 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.
