A high-capacity data cartridge features 200GB (or 400GB compressed) data storage in a single cartridge. The non-contact memory of 4KB inside the cartridge provides high-speed data search and supports cartridge management, particularly in library systems. High-coercivity, ceramic-armor metal particles enable the development of high quality and reliable data storage cartridges featuring high output, high S/N ratio, and low and stable error rate characteristics. High-precision, magnetic, servo signal recording technology allows the recording of servo track signals with greater accuracy and obtains excellent servo track signal characteristics through the increased data track density. Cartridge offers low error rates and improved, magnetic tape, physical properties.
