ABSTRACT:
An optical disc recording method comprises the steps of: setting a recording parameter function representing a relationship between a recording velocity for recording data to an optical disc and a parameter for optimally controlling a recording power controlling waveform for controlling a recording power of a light beam irradiated to the optical disc for recording the data; obtaining an optimal value for the parameter by executing a test recording at one recording velocity or at a plurality of recording velocities to a test area of the optical disc before actual data recording to the optical disc; correcting the recording parameter function in accordance with the obtained optimal value for the parameter; deriving the parameter corresponding to a recording velocity from the corrected recording parameter function; and recording the data by irradiating a light beam of the recording power controlling waveform to which the obtained parameter is applied.
