The cartridges had a total capacity of up to 8.5 TB. They were actually manufactured by the Fujifilm company, used Barium Ferrite (BaFe) magnetic particle technology to store the user data and were equipped with a Radio-Frequency IDentification (RFID) chip (for quick access to the cartridge metadata).\ The tape length inside of each cartridge is 1147 meters while it is only 5.2 microns thick. Once mounted in a tape drive, the media moves over the drive head at the speeds of up to 4.7 meters/second when reading or writing, but up to 13 meters/second when locating to a file. Since 2019, all data that had been stored on such cartridges have been copied onto more modern supports. As of 2022, CERN uses similar tapes produced by other suppliers and having a capacity of up to 20 TB.
