Disk-Compatible Multi-Layered Submicron-Holographic Data Storage

Digital reference imagery and mapping data are being extensively used for strike and mission planning, providing precise terrain positioning knowledge to the avionic objects to avoid obstacles or generate aim points. 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.
