Tensioning device for use with electromagnetic read/write transducing apparatus wherein a flat elongated band or strip of non-magnetic material is arranged adjacent to a plurality of read/record heads effective to support an item adapted to move between the heads and the tensioning strip and wherein the strip is lever actuated from a relaxed, released condition relative to the heads enabling easy removal and replacement due to wear or breakage into a taut condition and including means to prevent stray magnetic flux from one transducing device from interfering with the magnetic flux of another local transducing device effectively insuring a high level signal output.
A pressure pad for urging a document against a magnetic recording head has an elastameric belt with a low friction, wear resistant coating which urges the document against the head.
A modularized roller assembly for holding a flexible, magnetically encoded card moving in a feeding direction through a channel against a curved transducer surface.
