Holographic Computers

Holocomputers provide greater data storage, faster data access, and data processing flexibility than conventional electromagnetic computers. Compact disks save megabytes of information on a disc. Digital versatile disks provide sufficient storage space to fit an entire motion image on one disk. Nonetheless, with HDTV and increasing need for bigger media storage capacities, several research laboratories are working on the design and operation of working mediums for Holographic Disks (Holodisks) that can store data throughout the depth of a disk, not just on its surface. In the case of holographic data storage, it can be possible to store tens of terabits per cubic centimeter of optically sensitive media. Ideally, holographic information storage should have high data storing and retrieving precision, rapid speed, and data longevity. Another potential improvement of holotechnology disks is that they are more tough to pirate than traditional CDs or DVDs. This can be a security advantage for large-scale content distributors. The page on holographic technology and neural networks discusses additional topics.

Future generation generations of holotechnology data storage, holographic memory, and holotechnology data search processes may go beyond replacing DVDs and CDs. Holotech information processing may supercede magnetic hard drives as the primary format for computer data storage and information processing. Optical data analytic structures might become the primary information analytic structure for personal computers. holographic technology and microelectronics also has interesting notes.

For holotechnology data encoding, first a laser ray is divided in two. Then one of the resulting rays is passed through a Spatial Light Modulator (SLM) that converts configurations of electronic information into light and dark configurations in the laser beam. This beam becomes the "signal" ray. The second ray becomes the "reference" beam. Then the two rays are focused and intersected inside an optically sensitive storage media. This intersection initiates a chemical reaction between the storage media and the pattern of overlapping peaks and troughs of the two rays of light. This burns the data into the recordable media in the type of a hologram. To restore the data, a beam with identical wave phase and angle as the source reference ray is focused within the media, the signal ray is retrieved, and the white and black patterns are changed back into electronic data via the application of a Digital Camera Detector (DCD). Three-dimensional holotechnology data storage can store considerably more data in the same size object compared to surface-only, information storage systems such as present day CDs and DVDs. Linked page holographic technology and medical records also has useful information.

Holotech data storage and analytic structures may be able to provide data processing that is with far greater speed compared to present day two- dimensional systems. Two-dimensional data storage systems especially CDs and DVDs save and restore data in a linear sequence -- one bit at a time. Holographic information systems store and access information with parallel processing, an entire (million-bit) page of information at a time. Alternative page can be accessed at the same time by using different beam angles and wave phases. Beam inclination and wave phase can be modified much quicker than the mechanical motion required to read various fields in two-dimensional media. Holographic data processing is particularly promising for finding information in large quantities of information to identify patterns or relationships among information. The site on holographic data storage with polymers may also be of interest.
