摘要

为了进一步减小光磁混合存储记录位尺寸，建立了用于光磁混合存储记录介质的超分辨近场结构膜层模型、近场光场模型及温度场模型，采用有限元方法对超分辨近场结构光磁混合存储介质记录层的温度场进行了计算模拟。计算中采用的光磁混合记录介质膜层结构为C(2nm)/Sb(10nm)/SiN(10nm)/Co75Cr15Pt10(30nm). 当写入温度为550K时，随着入射激光功率的增加，光磁混合存储介质记录层温度场可写入区域面积增加。当激光功率从3.9mw增至6.9mw时，温度场可写入区域横向及纵向尺寸增加约1倍，记录密度减小至原记录密度的四分之一。

Abstract

In order to further reduce the recorded bit size of optical-magnetic hybrid recording

Super-resolution near-field structure (Super-RENS) thin film model

near-field optics model and temperature field model were built for optical-magnetic hybrid recording media. Finite element method was used to simulate the temperature distribution of the recording layer of Super-RENS hybrid recording media. The layer structure of hybrid recording media was C(2nm)/Sb(10nm)/SiN(10nm)/Co75Cr15Pt10(30nm). When the writing temperature was 550K

the temperature writable area of hybrid recording media increased with the laser power. When laser power increased from 3.9mw to 6.9mw

the sizes of temperature writable area in both vertical and horizontal directions doubled and the areal recording density decreased to a quarter.
