ABSTRACT:
A magnetic read/write head and backer plate assembly particularly for use for recording and reading information on a magnetics-on-film (MOF) layer in the image area of photographic filmstrips. The backer plate assembly overcomes the loss of compliance of the MOF layer to a head gap when the filmstrip is wrapped about the contoured surface of the magnetic head sufficiently to exceed the bending moment of the filmstrip. A relatively movable backer plate has a support region that assumes the contoured surface shape on engagement with the filmstrip emulsion layer opposite to the magnetic head and is curved until restrained at its free ends and restrained at a location in the support region opposite to the head gap by a resilient pad to thereby restore compliance along the line of contact of the head gap.
