A high-capacity data cartridge features 200 GB (or 400 GB 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. Offers low error rates and improved magnetic tape physical properties.
