  • System and method utilizing a conductive brush for providing power signals to a cartridge access device
    Patent number: 6941569
    Abstract: A cartridge access device in a cartridge storage system is designed to retrieve a cartridge from a storage device and to transfer the cartridge to a particular location within the system. Once the cartridge is no longer needed at the particular location, the cartridge access device retrieves the cartridge from the particular location and returns the data cartridge to the storage device. The data cartridge device preferably includes at least two engaging members that engage a respective surface of a frame assembly. Channels in the surfaces of the frame assembly guide the engaging members and, therefore, the cartridge access device as the cartridge access device moves. The engaging members are engaged with a respective conductive track member that extends through the channels in the frame assembly.
