AN OPTICAL POWER CALIBRATION METHOD FOR CALIBRATING THE WRITING OPTICAL POWER OF OPTICAL DISK DRIVE

摘要

The present invention discloses an optical power calibration method for calibrating a writing power of a compact disc drive. The compact disc drive has an access device for writing data onto the compact disc. The compact disc has a central portion, an inner power calibration area located outside the central portion, and outer power calibration area located outside the inner optical power calibration area for writing data. An outer power calibration area is set in the last possible lead-out area on the outer edge of the compact disc, and an optical power calibration area and an optical power calibration count area are also set in the outer power calibration. The access device is controlled to perform optical power calibration in the inner or the outer power calibration area and perform counting of optical power calibration in the inner or outer optical power calibration according to the position of the writing data in the abovementioned data storage area. <IMAGE>
