However, the digital files of these geodata are as large as petabytes or terabytes. Ultra-high data storage capacity and fast dissemination of these geodata within military and intelligence services are critical important for successful defense operations. Currently available data storage technologies have almost reached their physical limitation on both storage capacity and access rate. This severely limits real-time performance of military operations. Based on our encouraging preliminary study of micro-holographic data storage, New Span Opto-Technology Inc. proposes herein a novel data storage technique based on multi-layered wavelength-multiplexing micro-holographic recording (MWMR) which combines the technical advantages of both holographic recording and conventional disc storage. The approach can potentially reach several terabytes with a single small disc or up to petabytes with multiple-stacked disks. The Phase I research will focus on feasibility studies of the proposed MWMR-based concept. In Phase II, we will improve the system design and build a compact MWMR drive to demonstrate the functionality through ultra-high density recording of terabytes and petabytes data. Benefits: The successful development of the proposed MWMR technique will benefit the ultra-high data storage with fast data access for military strike and mission planning. The compatibility with conventional optical disk technologies enables local and ultimately laptop storage solution of reference imagery data for military applications in a variety of platforms. The proposed storage devices may also be embedded in various precision weapon systems due to compact size and light weight. The applications of geodata storage and access in military are wide, including navigation and guidance, missile seekers and warning, wide area surveillance, landmark tracking for precision landing and hazard avoidance, as well as providing reliable location and status of friendly forces. Apart from the military applications, there is a potential commercial market for a compact MWMR-based technology. Demand on high-density data storage has been exploded in civilian sector. A variety of data occupied storage spaces are being created every day. Technologies currently available for data storage have come to their physical limits and may not be able to meet future demands. The proposed project will benefit the development for next generation of data storage technology. In addition, the proposed technique may also have many other significant applications, such as commercial airline navigation, intelligent guidance systems for civilian vehicles, R&D for geology, seismology, as well as remote sensing.
