Discuss in brief the architecture of magneto optical disks.admin
Ans. The architecture or design of MO disks contain various layers of material, protective coating and laser beam. The design of MO disks defines the combination and the uses of anti-reflection layer, quadrilayers and amorphous metal. The anti-reflection layers are used to increase the light absorption. The quadrilayers are used to decrease the reflection of light that provides the facility to decrease the requirement of laser light. The amorphous metal is used as MO media. Fig. 1.20. shows the architecture of MO disks.
