Equipment (100) for coating photographic media (14), such as photographic film and paper, has an apparatus (10) for printing bar code indicia (12) on a moving photographic media and a printer means for printing human readable indicia (16) on the media. The printer (20a, 20b) moves into print position along a lateral edge (28) of the media (14) in response to input signals received from a controller (22) having computer readable medium for directing the printing and movements of the printer (20a, 20b).

Equipment for coating photographic media

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.
