| 术语 | magnetooptical (MO) recording |
| 释义 | magnetooptical (MO) recording 磁光记录法［技术］ A technique of recording information on the magnetooptical media. Writing is performed by reversing the polarization of the magnetic domain, while under the influence of an external magnetic field, by heating it above the compen sation point temperature with a short laser pulse. Reading is performed by measuring the Kerr effect, which rotates polarized light when it is reflected under the influence of a magnetic field. 在磁光介质上记录信息的一门技术。写入 是用短的激光脉冲把磁化区加热到高于补偿点温度,在外磁场作用下改变该区的磁化极性。 读出是利用克尔效应原理来判断。克尔效应是指在磁场作用下的反射偏振光的偏振面 会发生旋转,其旋转方向取决于磁场方向。 |
