2 February 1993 Parallel optical memories for very large databases
Author Affiliations +
The steady increase in volume of current and future databases dictates the development of massive secondary storage devices that allow parallel access and exhibit high I/O data rates. Optical memories, such as parallel optical disks and holograms, can satisfy these requirements because they combine high recording density and parallel one— or two—dimensional output. Several configurations for database storage involving different types of optical memory devices are investigated. All these approaches include some level of optical preprocessing in the form of data filtering in an attempt to reduce the amount of data per transaction that reach the electronic front—end
