CODE-ADAPTIVE MAGNETO-OPTICAL WRITE STRATEGY

摘要

The present invention relates to a method and apparatus for writing data to a storage layer of a magneto- optical recording medium using a laser beam of a predetermined power level (Pw) and a magnetic field modulated to at least two predetermined field levels (+Hw; -Hw) in accordance with said writing data. The predetermined power level and/or the at least two predetermined field levels are adjusted in dependence on a pattern of previously recorded data so as to compensate for stray field variations caused by run lengths of the previously recorded data pattern. Read-out jitter and errors can be reduced thereby.
