Abstract

Magneto-optical (MO) recording offers a new dimension in erasable mass data stroage technology. Typical recording layers in presently used MO disks consist of rare earth-transition metal alloys enveloped by silicon nitride protective layers. Characteristic low media noise of amorphous TbFe-based alloys make them particularly attractive for use in MO disk recording layers. The synthesis/microstructure dependence for their performance is the subject of this research.
