LC Concept was a 35 mm film projection sound format, developed in France and released in 1991. It used 5.25" 300 megabyte capacity re-writable magneto-optical disks to hold 4 or 5.1 channels of MUSICAM compressed audio. Two disks were used to hold approximately three hours of sound. The system was adopted in France, Belgium, and Switzerland. A large litigation against Universal Studios, Steven Spielberg and DTS frightened the investors. DTS had to buy the LC patents to resolve the issue. [1]
The system was developed by Pascal Chedeville and Élisabeth Lochen. A standard SMPTE timecode printed next to analogue soundtrack on the film print was read by a reader connected to the playback unit kept the playback in sync. The system was tested with a re-release of the Cyrano de Bergerac , and the first commercial release was Until the End of the World .

Basic Instinct , Free Willy , Falling Down , Cliffhanger , Backbeat , Silent Tongue , Boiling Point , Heaven and Earth , Cyrano de Bergerac , L.627 , The Lover , Until the End of the World , The Accompanist , IP5: L'île aux pachydermes , All the World's Mornings , Arizona Dream , La Belle Histoire , Bitter Moon .
