Magneto-optical recording requires optical discs that show relative square hysteresis loop and have coercivity greater than 1000 Oe. TbFeCo, a Rare Earth Transition Metal best fits the requirements for magneto-optical media. The disc for this project is made up of four layers deposited on a polycarb...
