Abstract

A tape reel assembly for maintaining a data storage tape. The tape reel assembly includes a first flange, a second flange and a hub ring. The first flange includes a first plate and at least one loop member extending in a generally axial fashion from an inner face of the top plate at a radius R1. The second flange includes a second plate and at least one leg extending in a generally axial fashion from an inner face of the bottom plate. The leg is positioned to selectively engage the loop member. Finally, the hub ring is provided separately and is free of material extending across an inner diameter thereof. The hub ring further defines an outer winding surface and inner surface having a minimum radius R2. The hub ring is assembled between the first plate and the second plate. In this regard, the radius R2 is greater than the radius R1 such that the loop member and the leg extend and interact within an area defined by the inner surface of the hub ring.
