<p>A magneto-optic recording medium records data in a single, direct-overwrite step. The medium includes a magneto-optical storage layer (32) and a magnetic biasing layer (36,38) disposed in selected heat conductive relationship with the storage layer. The first magnetic field is generated externally of the storage layer at a first energy level of a laser to set the magnetic orientation of domains at the storage layer. At a second energy level of the laser, which is higher than the first energy level, the magnetic biasing layer provides a second magnetic field greater than the first magentic field for setting the magnetic orientation of domains in the storage layer.</p> |
