Document Thumbnail

Optical sound track recording has a history of over 100 years. A survey of the fundamental steps of progress is given. The landmarks described include: the variable-density technique by Ruhmer; the technology and techniques of the Triegon system and its importance to the following development; the foundation of the Klangfilm GmbH by Siemens and AEG; and the Eurocard-recorder and the Klarton voiceless system. The origins of the analog stereophonic optical sound are discussed.
