Abstract:
1. A tape read/write head actuator for a tape drive system for a tape, comprising: a coil adapted to conduct an electric current to generate a magnetic field; 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 base having a first support frame; a lever pivotally coupled to said first support frame at a pivot point; a tape read/write head supported by said lever on a first side of said pivot point; a first permanent magnet supported by said lever on a second side of said pivot point opposite said first side wherein said magnet is positioned facing said return path structure so that magnetic attraction between said magnet and said return path structure biases said magnet and said tape read/write head in a first position relative to said first support frame, and so that 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 lever and said tape read/write head to pivot relative to said first support frame as a function of the magnitude and direction of said current through said coil.
