Abstract
Photographic elements are provided with a magnetic recording region, such as a stripe or layer, that is useful for sound recording, by applying a dispersion of finely-divided magnetic particles in a liquid medium to the element in a predetermined form and solidifying the dispersion by bringing the element into contact with an induction-heating apparatus. The apparatus comprises a rotatable cylindrical roller whose cylindrical surface engages the element and which is heated by induction only within a rim portion thereof so as to generate heat adjacent to the cylindrical surface for efficient transfer to the element.
