| 简介 |
A domain-wall-displacement-type magnetooptical recording medium is provided in which a floating magnetic field from a surrounding portion that operates on a recording/reproducing portion is suppressed. The recording medium includes a displacement layer having a composition such that rare-earth-element sub-lattice magnetization is dominant at room temperature, a switching layer, a memory layer, and a magnetization compensation layer in which iron-family-element sub-lattice magnetization is dominant at room temperature, for suppressing generation of a stray magnetic field at a temperature near room temperature. |
