ABSTRACT:
A photographic still camera for receiving an elongated filmstrip having a cross-film curvature and having a substantially transparent magnetic layer deposited on the film surface and recording or reproducing information on or from the magnetic layer in the image frame areas of the filmstrip. The filmstrip is transported from supply to takeup chambers between film rails and a backing plate past a camera image frame exposure aperture with the magnetic layer facing the backing plate and having a concave cross-film curvature near one side of the exposure aperture. A plurality of inverted gull wing shaped, spring flexure elements are positioned to extend across the magnetic layer at the side of the exposure aperture. Each flexure element has a fixed mounting plate attached to the backing plate coupled through an angled fixed leg to a mounting platform which in turn is coupled through a further angled leg back to a further plate such that the mounting plate is suspended toward the filmstrip magnetic layer. Magnetic recording head elements mounted to the mounting plates contact the magnetic layer across a variable spacing. Pitch motion is provided through the flexible legs in response to changes in filmstrip advancement tension. Roll motion compliance with the concave cross-film curvature is provided by a mounting platform gimball mechanism.
