Magneto-optical recording medium and manufacturing method thereof.

摘要

A magneto-optical recording medium has a recording layer including at least two magnetic layers. The magneto-optical recording medium satisfies a condition of ¦A1.K1 - A2.K2¦ < 2.0 (erg<2>/cm<4>) wherein A1, K1, A2, and K2 respectively represent an exchange constant of a first magnetic layer, a perpendicular magnetic anisotropy of a first magnetic layer, an exchange constant of a second magnetic layer, and a perpendicular magnetic anisotropy of a second magnetic layer. First and Second magnetic layers are made of TbFeCo. <IMAGE>
