holographic data retrieval

Shining a reference beam on hologram-engraved photosensitive material with the same angle and wavelength used to engrave the original holographic image causes light-bending action inside the storage media and recreates the holographic picture or encoded information. The holotechnology picture appears three dimensionally caused by the observed parallax. For information retrieval, the patterns of white and blackness from the retrieved picture are transformed back into electronic information with a detector array. Data retrieval is very rapid, often recreating an entire (million-bit) page at a time. See CFC International for expanded material about holotechnology.

Besides rendering quicker access and more capacity, holographic technology pioneers new means of information comparison and extraction. Many present day data recording and playback systems require precise details of data location in order to retrieve data and they process it in a linear sequence. In contrast, holographic technology enables searching large quantities of information an entire page at a time to contrast overall patterns and sameness of patterns. With holographic applied science, the degree of similarity between a high-level search configuration and data pages throughout an optical media depth can be measured without bit-by-bit analysis of individual data components. This is called "Associative Retrieval." Associative extraction is more compatible with imprecision and fuzzy logic, and more similar to human cognition, than traditional information storage and extraction systems. Linked page Virtualization also has developments regarding this topic.
