Abstract:
An optical disk recording apparatus for recording information onto a write-once or erasable optical disk, the apparatus comprising:a memory component including a table of prerecorded correction curves for each type of a variety of different optical disks with each of said correction curves consisting of recording power correction values corresponding to radial positions on each optical disk determined from the results of a prior running optimum power control (OPC) operation matched against the radial positions on each optical disk and stored in the memory component; a correction component for reading the correction value from the correction curves in the table corresponding to the radial position of the disk matching the address location on the optical disk at which the optical disk recording apparatus attempts to commence writing information and correcting the recording power in an optimum power control (OPC) operation at the matched address location using the correction value read from the correction curve; and a recording component for recording information onto the optical disk starting at the matched address location using the corrected recording power.
