摘要

磁光盘读写过程的重要因素是读出载波噪声比(C/N)高、读出信号包线平滑、光学效率高、磁头尺寸紧凑、磁头重量轻。本文综述了许多关于磁光头和磁盘衬底的光延迟影响的研究结果。介绍了磁光头和磁盘驱动系统的改进。

Magneto-optical Recording Readout Performance Evaluation

Important factors in read and write processes for magnetooptical disk are that readout carrier to noise ratio (C/N) is high, readout signal envelope is smooth,optical efficiency is high, head size is compact and head weight is light. This paper summarizes results from many studies on optical retardation influence in magneto-optical head and disk substrate. Improvements in a magneto-optical head and disk drive system are presented.
