Holographic data storage is a potential technology in the area of high-capacity data storage. While magnetic and optical data storage devices rely on individual bits being stored as distinct magnetic or optical changes on the surface of the recording medium, holographic data storage records information throughout the volume of the medium and is capable of recording multiple images in the same ...
With holographic storage, however, a different 'page' of information is accessed. Holographic storage uses two laser beams, a reference and a data beam, to create an interference pattern at a medium where the two beams intersect. This intersection causes a stable physical or chemical change which is stored in the medium.
Electronic quantum holography (also known as quantum holographic data storage) is an information storage technology which can encode and read out data at unprecedented density storing as much as 35 bits per electron. [1]
This is the top level category for all forms of holographic data storage. Pages in category "Holographic data storage" The following 7 pages are in this category, out of 7 total.
For holographic data storage, holographic associative memory (HAM) is an information storage and retrieval system based on the principles of holography. Holograms are made by using two beams of light, called a "reference beam" and an "object beam". They produce a pattern on the film that contains them both. Afterwards, by reproducing the ...
Two photographs of a single hologram taken from different viewpoints. Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry.
HVD is not the only technology in high-capacity, holographic storage media. InPhase Technologies was developing a rival holographic format called Tapestry Media, which they claimed would eventually store 1.6 TB with a data transfer rate of 120 MB/s, and several companies are developing TB-level discs based on 3D optical data storage technology.
Holographic Versatile Card. The Holographic Versatile Card (HVC) was a proposed data storage format by Optware; the projected date for a Japanese launch had been the first half of 2007, pending finalization of the specification, however as of January 2025, nothing has yet surfaced.This issue may be related to the bankrupt of certain entities once responsible for the development and ...
