【摘要】 针对信息存储低容量、低速率的现状,提出了将阵列激光器、波分复用技术(密集型波分复用)和多层镀膜相结合实现三维信息存储的方法。该方法利用光纤光学头的耦合物镜实现对光斑的自动近场聚焦,可实现海量信息的并行读写,并能极大地减少三维存储的寻道时间。对光电探测器检测的光信号幅度进行了计算机仿真分析,这种并行存储的探索是实现高密度、大容量的重要基础研究。更多还原

【Abstract】 This paper proposes that array laser, wavelength division multiplexing (density wavelength division multiplexing) and multi-magnetization layers storage are combined to realize 3D information storage. The coupling object lens of optical fiber head can auto-focus the optical spot in near field, so that enormous information can be written and read simultaneously, and the tracking time of three-dimension information storage can be reduced greatly. At the same time, the optical signal amplitude received by photo-electricity detector is simulated by computer in detail. The search of parallel storage mode is important and basic to realize high density and enormous capacity storage.更多还原
