The Hologram Computers of Tomorrow

Technology; The Hologram calculators of Tomorrow Researchers here are developing a computer computer storage system that could workshop the contents of thousands of books in a piece of material the size of a Scrabble tile. Moreover, the rising system could be fast bountiful to retrieve in one second an amount of information that would keep nowadayss computer disk drives occupied for five hours. The experimental memory device stores information using holograms, those shimmering three-dimensional images that are unremarkably seen on credit cards. It is under development at the Microelectronics and Computer Technology Corporation, a computer-industry consortium here usually know by the initials M.C.C. Holographic storage has been a dream of scientists for 30 years. Many of the ideas are nearly as old as hard disk magnetic transcription, said Glenn Sincerbox, a selective information storage expert for the International Business Machines Corporation, who worked on holographical memory in the 1960s. But while magnetic recording has blossomed into a huge industry, holographic storage has never emerged from the lab. Now, however, enough progress has been made that the nearly forgotten dream is universe revived. While there are still formidable obstacles, M.C.C.

researchers are confident that the Holostore, as they call it, will be usable later in this decade. Holographic storage differs from disk drives in three respects. * Disk drives store information in only two dimensions, on the flat surface of the disk. Holographic systems store information in three dimensions inside a regular hexahedron of special material, allowing them to pack more information into a accustomed space. * Disk drives have moving parts. It can take many thousandths of a second -- an eon for computers -- for the recording head to extend to the spot on the spinning disk where the desired entropy is stored. But holographic systems can be built with no moving parts and, using lasers, can find the postulate data in a millionth of a second. *...
