The antenna may be operated so as to determine the polarisation of any incoming signal, since the three feeds have polarisations at 120 degrees to each other. An UCR & black-generation processor performs density control on the CMY data by each color component, and performs under-color removal and black-generation processing on the density-controlled image data. A tape cleaning drive incapable of transferring data to and from the recording tape media which is independent of the tape drives, the tape cleaning drive disposed entirely within the tape cartridge library. The synchronous buck DC to DC converter cells are also arranged in pairs of synchronous buck DC to DC converter cells.
