Optical recording
http://matterwave.physics.berkeley.edu/optical-recording-of-biological-signals Most of the inventions which led to optical sound-on-film technology employed the use of an electric lamp, called an 'exciter', shining through a translucent waveform printed on the edge of a film strip. When the light shines through the film, it is read by a photo-sensitive material and fed through a processor which converts the photovoltaic impulse into an electrical signal that is then amplifie…
