James T. Russell (born 1931) is an American inventor. He earned a BA in physics from Reed College in Portland in 1953. He joined General Electric 's nearby labs in Richland, Washington , where he initiated many types of experimental instrumentation.
Russell had found a way to record digital information onto a photosensitive plate in tiny dark spots, each spot one micrometre from centre to centre, with a laser that wrote the binary patterns. Russell's first optical disc was distinctly different from the eventual compact disc product: the disc in the player was not read by laser light.
Optical video recording technology, using a transparent disc, [6] was invented by David Paul Gregg and James Russell in 1963 (and patented in 1970 and 1990). [7] [8] The Gregg patents were purchased by MCA in 1968. By 1969, Philips had developed a videodisc in reflective mode, which has advantages over the transparent mode. MCA and Philips then ...
Both Gregg's and Russell's disc are floppy media read in transparent mode, which imposes serious drawbacks, after this were developed four generations of optical drive that includes Laserdisc (1969), WORM (1979), Compact Discs (1984), DVD (1995), Blu-ray (2005), HD-DVD (2006), more formats are currently under development.
American inventor James T. Russell is known for inventing the first system to record digital video information on an optical transparent foil that is lit from behind by a high-power halogen lamp. [1] [2] Russell's patent application was first filed in 1966, and he was granted a patent in 1970. Following litigation, Sony and Philips licensed ...
[7] [8] It is debatable whether Russell's concepts, patents, and prototypes instigated and in some measure influenced the compact disc's design. [9] The compact disc is an evolution of LaserDisc technology, [10] where a focused laser beam is used that enables the high information density required for high-quality digital audio signals. Unlike ...
David Paul Gregg (March 11, 1923 – November 8, 2001) was an American engineer. He was the inventor of the optical disc (disk). Gregg was inspired to create the optical disc in 1958 while working at California electronics company Westrex, a part of Western Electric.
