Patent ID: 7046599

Claim:
An optical disc recording method wherein an optical disk is rotated at constant angular velocity (CAV) and data is recorded to a recording area of the optical disc by continuously increasing, from an inner track side to an outer track side of the optical disc, a recording velocity for recording data and, simultaneously, continuously strengthening a recording power of a light beam irradiated to the optical disc for recording the data, the method comprising the steps of: (a) allocating a plurality of CAV zones to the recording area of the optical disc and assigning a recording power function in the form of a linear function to each CAV zone which recording power function represents a relationship between the recording velocity and an optimal value of the recording power of the light beam, and setting a coefficient that represents a relationship between slopes of the recording power functions; (b) obtaining an optimal recording power by executing a test recording to a test area of the optical disc at two recording velocities which are corresponding recording velocities in a predetermined zone before actual recording of data to the optical disc; (c) obtaining the slope of the recording power function of the predetermined zone in accordance with the obtained optimal recording power and correcting the slopes of other zones in accordance with the corrected recording power function of the predetermined zone and the coefficient; (d) deriving a recording power corresponding to a recording velocity using the corrected recording power function and the corresponding recording velocity; and (e) recording the data by irradiating a light beam of the obtained recording power.
