| 摘 要： | 设计了一种新型一体化光学飞行头，通过对光学飞行头滑块气浮力分布和飞行姿态(飞行高度、仰俯角和滚动角)的数值仿真分析，对滑块气体轴承表面(ABS)形貌参数进行了优化设计，确定了滑块的主要结构参数．仿真结果表明，所设计的光学飞行头滑块的飞行高度能够在光盘的不同半径处保持在43-44nm之间，符合近场光存储系统的信号读写要求．该光学飞行头具有良好的机械性能和光学性能，可在近场光存储系统的读写过程中获得稳定的飞行高度和高信噪比的光学信号．

| Abstract: | A new structure of integrated optical flying head (OFH), with both perfect mechanical and optical performance, is designed, which can achieve stable flying height and high signal/noise ratio optical signal during the read/write motion in near field recording (NFR) system. Air bearing surface (ABS) design and optimization are discussed by means of numerical simulation of pressure distribution and flying attitude , i.e., flying height, pitch and roll, the primary parameters of ABS for OFH slider are simultaneously presented. The simulation result demonstrates that the flying height of the integrated OFH slider remains stable within 43 nm and 44 nm at various radium of optical disk to meet the requirements of NFR system. |
