近场记录光盘是一种新的光盘记录技术，它有二个特点：１）极高的记录密度；２）很高的寻道速度。本文介绍了近场光盘记录技术的特点；提出了近场光盘记录技术中动态条件下读写系统中的写入能量问题；对头盘间的能量传输问题进行了仿真计算。
Near field recording disc is a new optical disc recording technology, which has two characteristics: 1) very high recording density; 2) high seek speed. This paper introduces the characteristics of near-field optical disc recording technology; puts forward the writing energy problem in the near-field optical disc recording technology under the dynamic condition of the reading and writing system; and carries on the simulation calculation of the energy transmission between the head disc.
