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 ...
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.

With an interest in lasers, Russell soon began his research in an optical system that would replace a phonograph's needle and replace it with a laser that would read codes in order to record and playback sound.[173][174] At 12 inches (30 cm) in diameter, Russell in 1970 had successfully invented and built the world's first compact disc that ...
