A data storage tape cartridge including a housing, a tape reel assembly, a brake assembly, a centering device, and a storage tape. The tape reel assembly includes a hub, opposing top and bottom flanges, and drive teeth. The drive teeth extend in an axial fashion relative to the hub and are provided for engagement by a tape drive chuck. The centering device is provided to support the tape reel assembly in a centered position relative to the tape reel opening in the locked state. The centering device includes a rib and a corresponding groove. The rib is formed by one of the bottom flange and the base, whereas the groove is formed by another of the bottom flange and the base. The groove is configured to selectively receive the rib, thereby supporting the tape reel assembly in the center position. The centering device prevents the tape reel assembly from laterally shifting relative to the tape reel opening when the data storage tape cartridge is vertically oriented.
