Abstract
The first report on the discovery of the infrared transparency of magnetic tracks was published in the September 1957 Journal. In this Progress Report the author discusses further tests, the effect of the thickness of the magnetic oxide deposit upon its transmittance, and the results of intermodulation measurements on a 35mm reproducer converted for utilization of the transparency effect. Films which demonstrated the application of the phenomenon for bilingual and stereophonic recordings, and the modification of a projector for the use of such films, are described.
