1. A tape movement constraint for a tape drive system for a tape, comprising:

  • a base having a first support frame;

    a coil supported by said first support frame and adapted to conduct an electric current to generate a magnetic field wherein said first support frame includes a return path structure formed of a magnetically permeable material, and positioned adjacent said coil to conduct said magnetic field generated by said coil;

    a second support frame pivotally coupled to said first support frame;

    a first permanent magnet supported by said second support frame wherein said magnet is positioned facing said return path structure; and

    a tape roller barrel rotatably supported by said second support frame, said roller barrel being positioned along a tape path;

    wherein magnetic attraction between said magnet and said return path structure biases said second support frame and said roller barrel in a first position relative to said first support frame and wherein current conducted through said coil generates a magnetic field which is conducted by said return path structure to interact with the magnetic field of said magnet which causes said second support frame and said roller barrel to pivot relative to said first support frame as a function of the magnitude and direction of said current through said coil.
