High-performance optical disk systems for tactical applications

Haritatos, F.

The Rome Laboratory (RL) has been actively pursuing the development and transition of optical disk storage technology from the laboratory into the real world environment. A cosiderable investment of R&D resources has been made by the Department of Defense with an emphasis on the development of high-capacity, high-performance systems. Optical disk storge offers several advantages which are critical to tactical military applications. These advantages include: high data storage capacity, immunity to head crashes and data loss due to vibration and shock, fast random data access, removable recording media and reduced susceptibility to nuclear radiation effects. A rewritable storage materials, based on magneto-optics (M-O) technology, was selected since it provides a user with the ability to read, write and erase digital data. Currently, the TODS equipment suite will use both 5.25 and 14-inch diameter recording material on a glass substrate for better performance under military conditions. Under the Tactical Optical Disk System (TODS) project, three rewritable optical disk systems are under development and undergoing integration within operational Air Force aircraft.
