Abstract
A tape reel assembly for use with a data storage tape cartridge. The data storage tape cartridge includes a housing, a tape reel pin, the tape reel assembly, and a storage tape. The tape reel assembly is rotatably associated with the tape reel pin and includes a hub, a spherical piece and a sleeve. The spherical piece is insert molded within an axial bore of the hub and provides a thrust surface. The sleeve is also insert molded within the axial bore of the hub and provides a journal bearing surface. In accordance with a method of the present invention, the tape reel assembly is formed as part of an injection molding process, whereby a core pin precisely positions the spherical piece and co-axially centers the sleeve relative to an outer, tape winding surface of the hub.
