Abstract
In a photographic apparatus which handles film having a magnetic layer on one side for magnetically storing data on the film, a photographic film transport mechanism including a magnetic head suspension system that allows balanced roll motion of two magnetic heads while in contact with the nonplanar magnetic recording surface of film, and allows for in contact magnetic recording during transfer of data only, with release of the contact pressure at all other times, the mechanism comprising: a platen for confining film that is transported past the platen; a cantilever spring having one end fixed to the platen and a free end, the spring extending in the direction of transport of the film; a pair of magnetic heads; means for mounting the pair of magnetic heads side-by-side on the free end of the cantilever spring which allows the heads to rotate about a roll axis parallel to the film transport direction; and means coupled to the free end of the spring for moving the heads into and out of contact with the film.
