Abstract :
Magnetic Multi-Valued (MMV) recording process is studied by numerical simulation including thermomagnetic effect. A medium, which consists of PtCo capping layer coupled to TbFeCo recording layer, switches the signal of Kerr rotation angle responding to the external field in four levels. The time evolution of generated pattern of recording mark is calculated by extending the previous magneto-optical (MO) recording simulation for single layer system
