Abstract :
Simplicity of equipment required and adaptability of the process to 8-millimeter as well as 16- and 35-millimeter film are among the advantages claimed for magnetic recording of sound on motion picture film. Experimentally converted conventional projectors that can be used as recorders also are described.
