Abstract:
In a data storage library having a plurality of cells for holding media cartridges for use in storing data, at least one media drive, a robotic device for transporting cartridges between the plurality of cells and the at least one media drive in the data storage library, and a controller for controlling the robotic device, a system for transmission of communication signals between the controller and the robotic device, the system comprising:a substantially planar electrical insulator having opposed first and second sides; a first substantially planar electrical conductor on the first side of the insulator for use in providing electrical power to the robotic device, the first conductor to be provided with an electrical charge and having a width; a second substantially planar electrical conductor on the second side of the insulator for use in providing electrical power to the robotic device, the second conductor to be provided with an electrical charge opposite the electrical charge of the first conductor, the second conductor having a width; and means for generating the communication signals for transmission between the controller and the robotic device on one of the first and second conductors, wherein the width of the second conductor is less than the width of the first conductor, and the second conductor is substantially centered on the second side of the insulator relative to the width of the first conductor to reduce fringing of an electromagnetic field resulting from a transmitted communication signal.
