Camera apparatus for magnetically recording on film
First Claim
1. A photographic still camera for transporting a photographic film over an exposure opening to expose frames of the film, the film having a magnetic surface on one side for magnetically recording information on the film, said camera comprising:
- a camera body having an exposure opening;
a film platen supported to engage the film and retain it in an exposure plane adjacent said opening; and
a magnetic head mounted at said platen to engage the magnetic surface of said film in said plane.

Abstract
Magnetic recording apparatus for a photographic still camera comprises a fixed magnetic head mounted on a film platen. The head is adapted to contact a magnetic coating on the film adjacent the image area of the film. A pressure pad is mounted in the camera on the opposite side of the film and positioned in close proximity to the film. The pressure pad is biased by a spring to apply pressure on the head through pressure on the film to assure that the film is in intimate contact with the head when the film is advancing. During film exposure when the film is stationary, the pressure pad is retracted to avoid distortion of the image plane.
