Electronic Comparator for the Automatic Inspection of Magnetic Sound Prints

Jerome W. Stafford

This paper describes an electronic system for comparing magnetic sound prints with the master track during the printing operation. In the release printing of CinemaScope pictures the comparator is a useful tool for the automatic inspection of the product. It has been in service at Metro-Goldwyn-Mayer Laboratory since December 1953 and has proved to be of great value in making CinemaScope prints.
