Patent ID: 7345976

Claim:
A method for recording data in an optical recording medium wherein the optical recording medium includes a substrate, a protective layer and a plurality of information recording layers between the substrate and the protective layer, the method for recording data in an optical recording medium comprising: projecting a laser beam onto the plurality of information recording layers whose power is modulated between at least three levels including a level corresponding to a recording power, a level corresponding to an intermediate power lower than the recording power and a level corresponding to a bottom power lower than the intermediate power onto at least one information recording layer other than an information recording layer farthest from the light incidence plane; and forming a recording mark in the at least one information recording layer other than the recording layer farthest from the light incidence plane, thereby recording data therein, wherein the power of the laser beam is set to the bottom power when it is projected onto the end potion of each of the recording marks, and, wherein the power of the laser beam is modulated so that a time period during which the power of the laser beam is set to the bottom power for forming the end portion of each of the recording marks becomes longer as a linear recording velocity is higher.
