ABSTRACT:
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.
