MAGNETO-OPTIC RECORDING MEDIUM HAVING MAGNETO-OPTIC FILM LAYERS SEPARATED BY YTTRIUM OXIDE

摘要

A magneto-optic recording medium (12, 100) including a transparent substrate (14) and a magneto-optic stack provided thereon. The stack includes a plurality of magneto-optic film layers (20, 30, 40, 50, 60, and 70) less than 10 nm thick. Adjacent magneto-optic film layers are separated by dielectric layers (25, 35, 45, 55, and 65) consisting essentially of Y2O3.
