• LTO-Ultrium Universal Cleaning Cartridge is compatible with all manufacturers' LTO Ultrium 1, 2, 3 and 4 drives and provides up to 50 cleanings or as many as your particular drive allows
• Cleaning is done by shuffling a specific amount of tape over the drive head based on a specific cleaning algorithm that is unique to each drive manufacturer
• Cleaning reduces built-up or stains that get deposited on drive heads and should be done whenever the drive's "use cleaning cartridge" signal is flashing
• It is recommended that you keep track of the number of times you use the cartridge and discard it after it reaches the maximum number of uses for your drive model
• In addition, the cartridge has an RF (radio frequency) LTO-CM (cartridge memory) that keeps track of the number of times your cartridge has been used
• Most drives will read the CM, see when your drive has been used the maximum number of times, and will no longer use that cleaning cartridge.
