This Small Business Innovation Research (SBIR) Phase 1 project will develop a novel removable ultra high capacity micro optical storage device. The technology is based on a small form factor optical storage (SFFO) achieving 0.5 GB/disc using 32mm molded disc technology leveraged from DVD infrastructure. We propose a 11 to 22 times increase using Near Field Recording (NFR) employing a high index micro Solid Immersion Lens (microSIL). Information storage density is critically dependant on the smallest mark that can be reliably read with a focused spot (size~?/n?sin?) where n is the index of refraction, ? is the wavelength and ? describes the cone angle of the focused beam. A microSIL of GaP with n=3.3 at ?=650 nm shrinks the linear spot size by 3.3X yielding an areal density increase of 3.32 or ~11X. Increasing sin? from 0.60 to 0.85 gives another factor of two for 22X overall or 11GB/disc. Electron beam media mastering, MEMS semiconductor grayscale microSIL etching processes plus this novel front surface micro optical system technologies makes this system conceivable. We propose to integrate a GaP microSIL into our dynamic spin stand tester incorporating all the necessary read and write optics and electronics to develop sufficient understanding to make concrete commercialization plans.The commercial applications for a 10+ GB capacity low cost removable optical cartridge in the portable electronic device market are growing at an unprecedented pace as applications once reserved for desktops and workstations find their way onto portable platforms. This digital convergence is driving the mobile market arena. It provides majornew opportunities for storage and delivery of entertainment, educational content, movies, music, still photography and individual medical records. Today content is provided almost exclusively on large-format optical discs (CD/DVD), a new small form factor optical standard is positioned to capitalize on the existing infrastructure and existingconsumer habits. Still photo and video mobile phone cameras alone are estimated at 300 million units in 2006.

这个小型企业创新研究（SBIR）第一阶段项目将开发一种新型的可移动超高容量微型光存储设备。该技术基于小尺寸光学存储（SFFO），使用DVD基础设施中的32 mm模压光盘技术实现0.5 GB/光盘。我们提出了一个11至22倍的增加，使用近场记录（NFR）采用高折射率微型固体浸没透镜（microSIL）。信息存储密度主要取决于可以用聚焦点可靠读取的最小标记（尺寸~？/你好吗？sin？）其中n是折射率，？波长和？描述了聚焦光束的锥角。GaP的microSIL，n=3.3，在？= 650 nm使线性光斑尺寸缩小3.3倍，产生3.32或~ 11倍的面密度增加。增加罪？从0.60到0.85给出了另一个因子2，用于22倍整体或11 GB/光盘。电子束媒体母版制作、MEMS半导体灰度microSIL蚀刻工艺加上这种新颖的前表面微光学系统技术使该系统成为可能。我们建议将GaP microSIL集成到我们的动态旋转台测试仪中，并结合所有必要的读写光学器件和电子器件，以充分了解并制定具体的商业化计划。GB容量的低成本可移动光学盒在便携式电子设备市场上正以前所未有的速度增长，因为曾经为台式机和工作站保留的应用程序找到了它们的出路，便携式平台这种数字融合正在推动移动的市场竞技场。它为娱乐、教育内容、电影、音乐、静态摄影和个人医疗记录的存储和交付提供了新的机会。今天的内容几乎完全是在大格式光盘（CD/DVD）上提供的，一种新的小尺寸光学标准被定位为利用现有的基础设施和现有的消费者习惯。2006年，仅静态照片和视频移动的手机摄像头就估计有3亿台。
