Abstract
A corner roller for a belt-driven tape cartridge consists of an outer wall which contacts a drive belt in the cartridge and an inner wall attached to the outer wall. The inner wall includes a stepped axial bore which engages a shaft attached to a baseplate of the cartridge. A small diameter region of the axial bore forms a journal bearing surface for the shaft, and this surface preferably has a length and orientation with respect to the cartridge baseplate sufficient to symmetrically distribute on the journal bearing surface a load exerted on the corner roller by the cartridge belt.
