ABSTRACT:
Apparatus and a method are provided for easily, visually indicating to a user that a tape cartridge has reached the end of its useful life by causing a flag, wound beneath a tape inside the cartridge, to appear within a clear window in the cartridge housing. When a tape drive in which the cartridge is mounted detects a defect in a data tape, the tape is rewound and extra torque is applied thereto to expose the flag. When a cleaning tape reaches its end, the flag is released.
