A single reel data tape cartridge includes a base and a cover. The cover includes a rear wall, two opposing side walls, a front wall, and an upper wall connecting the rear, front, and side walls. The upper wall has an upper surface and a lower surface. A leader block area is formed in one of the corners of the upper wall and a strengthening rib is formed on the lower surface of the upper wall adjacent the leader block area. The strengthening rib partially encloses the leader block area. The portion of the upper wall adjacent the strengthening rib and outside of the leader block area is at least thicker than the portion of the upper wall in the leader block area.
