With the invention of first laser before 50 years has been proved generation of intense, focused and narrow light beam of
one wavelength, also at the same time were fulfilled assumptions for creation memories on light base - Optical Data
Storages. Contemporary dynamic memories operate on base electrical impulses, manufactured as matrix arranged
MOSFET transistors with capacitors, and reach time delay (latency time) in ones nanoseconds. Transfer data rates are
above ones of Gbps. Current storages are approaching technologically threshold parameters, what may be barrier to
further development, whereas Optical Data storages multiple exceed transfer data rates of contemporary memories, not
require reverse O/E/O signal transformation, operate in pico-seconds (ps) and work at low energetic levels of femto-
Joules. New end-user services lay still bigger emphasis for transferred and stored data volumes, transfer rates, quality of
transmission and data processing, whereby they partly pushing out contemporary storages and create place for optical
memory elements used in telecommunication networks and in devices. Optical storages with their several-fold higherdensity,
high transmission rates, better quality and small dimensions are becoming a new trend for dynamic buffer or
balancing memories, used for long-term data archiving in plasmonic nano-structures within Holographic Data storages.
