“The world’s appetite for high-performance mass storage grows exponentially. Today’s advanced computing systems are only marginally served by existing mass storage products, despite the remarkable advances in the 1980s of magnetic, optical and semiconductor devices. Hence, great interest is focused on beam-addressable and wavelength- or frequency-selectable optical memories that simultaneously provide very large capacities, fast random access and very high I/O rates.”
