Magneto-optisches Aufnahmemedium für kurze Wellenlängen

摘要

A magneto-optical recording medium for short wavelength in which a dielectric layer, a reproducing/recording bilayer made of (Ndx(TbFeCoCr)100-x/(TbFeCoCr) or (NdaGdb(TbFeCoCr)100-(a+b)/(TbFeCoCr), a protective layer and a reflective layer are, in sequence, formed on a substrate, which is superior in magnetic and magneto-optical properties at a short wavelength range in addition to being of high data storage density, high data transfer rates and long data archival capability.
