Comtrak—Combination Photographic Soundtrack

Abstract: Comtrak is a compatible photographic soundtrack which combines monophonic academy sound with four-track stereophonic sound. It is a photographic multiple-track format that combines pulse code modulation, variable area, and push-pull recordings. It is based on the earlier described Colortek system. The CCD scanner of that system and the reading technology with weave correction, and other remedial facilities are retained. Eight tracks make up the new Comtrak system, which delivers selectively either academy monophonic reproduction, or four or five separate tracks of high-quality stereo. The SMPTE time code is used for electronic character display below the theater screen or on a television screen. A single print inventory satisfies all the requirements for theatrical exhibition and distribution.
