Abstract:
1. A recording control method for an optical disk recording apparatus for recording data by irradiating a laser beam on an optical disk in one of a constant angular velocity (CAV) mode and a constant linear velocity (CLV) mode, the method comprising: reproducing control data from a control data area of the optical disk, and extracting recording parameters from the control data to create a recording parameter table; performing test writing at two or more radius positions of the optical disk, based on the recording parameters extracted from the control data, to correct the recording parameters in the recording parameter table; performing recording data, in the CAV mode, from an inner circumference of the optical disk toward an outer circumference thereof based on corrected recording parameters in the recording parameter table; interrupting the recording, during an interrupting period, when a change from the CAV mode to the CLV mode occurs during the recording in the CAV mode, and calculating a recording linear velocity at a point of change from the CAV mode to the CLV mode; calculating a recording parameter corresponding to the calculated linear velocity based on the corrected recording parameters in the recording parameter table during the interrupting period; replacing the corrected recording parameters in the recording parameter table for the outer circumference of the optical disk from a radius position at the point of the change, with the calculated recording parameter during the interrupting period; and resuming recording data, in the CLV mode, based on the replaced recording parameter.
