GE has been developing high performance recording systems for ruggedized and militarized applications, covering spaceborne, airborne, shipboard and mobile applications. Through sponsorship of the Air Force's Rome Air Development Center (RADC), the 14-inch Tactical Optical Disk System (TODS) is currently being designed and built for reconnaisance aircraft applications. These applications required real time data capture and online storage of large image and sensor database files, high must be stored and retreived rapidly. This requirements translates into high performance system specifications for the 14-inch TODS optical disk storage system. Of primary concern is high, continuous data transfer rates and large data storage capacities. Large image files cannot be segmented, thus requiring the system to contain the entire data file on a single media unit, and to stream the file at a very high data transfer rate. The 14-inch disk drive unit will store 12 gigabytes of user data on a double sided 14-inch magneto-optic rewritable disk. It will transfer data at rates up to 50 Mbps to/from the disk across two parallel optical channels. Continuous data transfer rates of up to 25 Mbps can be transfered across the system interface for the entire disk side (i.e. 6 gigabytes). This performance is delivered while operating in a MIL-E-5400 reconnaisance aircraft environment.
