A film cleaning apparatus and method includes a cleaning member with at least one self-loading cleaning surface or pad mounted directly over the film, such that when assembled, the cleaning surface or pad applies a force onto the film. The cleaning member of the present invention is preferably provided upstream of a magnetic head with respect to a direction of travel of the film in an imaging apparatus. The cleaning member of the present invention contacts the film with a sufficient load or force to clean the film and preferably, the opposing magnetic tracks of the film, prior to the film passing the magnetic heads or reaching the magnetic head area.

Photographic film cleaning apparatus and method

A method and apparatus for reading and/or recording information on a photographic element having a thin magnetic layer. The apparatus includes a magnetic head assembly having a read and/or write head having an outer engaging surface for contacting the magnetic layer. The outer engaging surface has at least one pole for reading or writing information on the magnetic layer and a protective layer and is made of a material having a Vickers hardness equal to or greater than 1000 kg/mm.sup.2. A spring is provided for applying a substantially perpendicular loading force between the photographic element and the magnetic read and/or write head. The substantially perpendicular loading being equal to or greater than about 10 gm/mm.sup.2.
