MAGNETIC INFORMATION MEDIUM Russian patent published in 1999 - IPC

FIELD: information processing and computer engineering, in particular, MO storage equipment for computers and home appliances. SUBSTANCE: device has substrate over which alternating dielectric and magnetic layers with perpendicular magnetic anisotropy are applied. Layer over substrate and intermediate layers are designed as GeO layers. Reflecting layer is designed as DyFeCo magnetic layer. EFFECT: increased Kerr effect of magnetic polarization, increased magnetooptical Q-factor in waveband of 0.78-0.82 nm for reading from substrate side. 1 dwg, 1 tbl
