METHOD FOR RECORDING INFORMATION ON OPTICAL RECORDING MEDIUM, INFORMATION RECORDER, AND OPTICAL RECORDING MEDIUM

摘要

A method for recording information on a rewritable optical recording medium having information recording layers by making a recording mark having a favorable shape. In the method, a laser beam which is modulated into a beam having powers including at least a recording power (Pw) and an erasing power (Pe) is applied to the light incidence surface (13a) of an optical recording medium (10) having at least an LO layer (20) and an L1 layer (30) formed thereon in a multilayer structure so as to record information. The relation between the wavelength lambd of the laser beam and the numerical aperture NA of the objective for focusing the laser beam is lambd/NA <= 700 nm. The ratio (Pe/Pw) of the recording power for recording information in the L0 layer (20) to the erasing power is set to a value smaller than the power (Pe/Pw) of the recording power for recording information in the L1 layer (30) to the erasing power.
