Holographic Disks

Holographic disks (Holodisks) store data three-dimensionally in photosensitive disks using holographic technology. In addition to more rapid access quickness, holographic data storage and analytic structures also provide much more storage capacity than two-dimensional systems. With two-dimensional media, only the top is used to store information. Although blue laser and nanotechnology are enabling enhancements in information density, the requirements of expected uses may exceed the constraints of two- dimensional magnetic and optical data storage compression. Holotech information storage and processing "break the top barrier" because different pages of information are stored in three dimensions in overlaid layers throughout the depth of the recordable media. Thousands of holotechnology pages can be saved on one holocube or holodisk. Alternative page are stored and accessed using reference rays with different projection angles or wave phases. Data storage density for 3D holotechnology systems is orders of magnitude more than that of 2D systems. holographic data storage breaks the surface barrier deals with related topics.

Traditional means of human to computer interaction built on keyboard and mouse, and speech input will tend to be seen as bottlenecks in the transmission of human to computer communication and there will be growing movement toward the "broad-band" body-computer communication made possible by medichips with direct neural-computer connections.

Besides rendering faster access and greater capacity, holotechnology applied science opens up new means of information comparison and extraction. Most current data recording and playback systems require exact specification of information location in order to retrieve data and they process it in a serial manner. On the other hand, holographic applied science enables searching massive amounts of data an entire page at once to compare overall configurations and sameness of content. With holotechnology applied science, the relative match between a high-level search pattern and data pages throughout an optical media depth can be measured without discrete comparison of specific information components. This is known as "Associative Retrieval." Associative retrieval is more tolerant of lack of precision and fuzzy logic, and more similar to human cognition, than traditional data recording and playback systems. holographic technology and neural networks discusses some of these issues as well.

Potential configurations for holotechnology storage media have holotechnology disks (Holodisks or HoloCDs) and holocubes (Holocubes). Among the challenges is that holodisks and/or holocubes must be accessible to light, but additionally solid in construction. When optimized, these media may contain more than an entire terabyte of content. The commercial market for holodisks and/or holocubes could grow to several billion dollars by 2010.
