Abstract: A model for the write process in exchange coupled direct overwrite magneto-optic media is presented. The exchange coupled interface between layers is accounted for with a domain wall energy when the transition metal spins in the top and bottom layer are not aligned. Magnetic layer properties suitable for direct overwrite are explored. Conditions under which overwrite fails or written domains are unstable are examined.
