Abstract
Abstract A method for recording laser written information on motion picture film includes creating a visual image on the film photographically. A laser records sound information on a direct-read-after-write optical storage strip on an edge of the film. In one embodiment, the strip is made of reflective silver particles in a gelatin matrix. Different tracks may have different sound information such as foreign languages or stereophonic sound. Editing information is also writable on the strip.
