A system and method for transmission of communication signals between a controller and a robotic device in a data storage library. The system and method include a substantially planar electrical insulator having opposed first and second sides, and first and second substantially planar oppositely charged electrical conductors on the first and second sides of the insulator for use in providing electrical power to the robotic device. The system and method also include circuitry for generating the communication signals for transmission between the controller and the robotic device on one of the first and second conductors. 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.

System and method for transmitting communication signals to an automated robotic device in a data storage system

Brush failure detection on a robotic device for use with a data storage library is accomplished through the use of two brushes drawing power from the same conductor. For example, each brush conducts electrical current between the robotic device and a conductor. Electronics determine operating status of each brush based on a measurement of the difference in current conducted through each brush in the pair of brushes.

Automated storage library brush failure detection

A system and method for distributing electrical power to an automated robotic device for transporting media cartridges in a data storage library. A power distributor includes multiple sections having first and second electrical conductors. A first power supply powers the first and second conductors of each section of the power distributor, and is connected to the first and second conductors of at least two section of the power distributor. A second power supply powers the first and second conductors of each section of the power distributor, and is connected to the first and second conductors of at least two sections of the power distributor. Power to each section of the power distributor is maintained in the event of a failure of one of the power supplies, and in the event of an electrical discontinuity in the power distributor.
