A system and method for overwriteable magento-optical recording comprises a medium having a data layer and a reference layer. The medium is heated with a laser pulse of short duration which causes a temperature gradient between the data layer and the reference layer. The temperature of the data layer becomes greater than the Curie temperature of the data layer, but the reference layer remains at a temperature below the Curie temperature of the data layer. The magnetic orientation of the reference layer thus remains unchanged and the data layer will orient itself in the same direction as the reference layer. It is therefore not necessary that the Curie temperature of the reference layer be greater than that of the data layer.
