breaking the surface barrier with holographic data storage

Holographic data storage and processing breaks the "surface barrier" because various pages of information are stored and accessed three-dimensionally in overlaid strata throughout the depth of storage media. Thousands of holographic image pages can be saved in one holographic cube. Alternative page are stored and accessed using reference rays with various projection angles or wave phases. Data storage compression for 3D holotechnology systems might be 10 or 100 times greater than that of two- dimensional optical or magnetic systems. For more about holotechnology, see also Digital Holographics .

Scientists at research laboratories are working toward science that could make television with holographic projections (holovisions) that can project animated, three-dimensional images beyond the constraints of the device. Genuine holographic motion picture applied science lets people see travelling, three- dimensional pictures without the need for special glasses. One method of creating animated holotechnology pictures is to send laser light by means of a lithium niobate waveguide covered by piezoelectric material. A modulator transforms video signal into vibrations of the piezoelectric material that, in turn, alters the direction of the light ray going through it. When this beam is projected into a translucent volume, it creates a 3D moving image. Also, Virtual Reality has interesting notes.
