High power controlling system for magneto-optical storage system

摘要

An optical storage medium processing method where a high power process is conducted upon the power adjusting area of the optical storage medium (which is used to perform optical beam power adjustment) by repeatedly conducting information recording by repeatedly radiating the optical beam at a power that is higher than that used for normal recording or erasing operations. The present invention enables highly reliable high density recording through accurate control of the laser power during the recording operation, in each area of the optical storage medium, regardless of the frequency of write and erase operations performed on each area.
