A tape guide roller, for use with a tape drive that is configured to receive a length of tape, includes a roller body having an outer surface with one or more grooved areas and one or more non-grooved areas. The one or more grooved areas make up seventy-five percent or less of the outer surface, and the one or more non-grooved areas make up at least twenty-five percent of the outer surface. Furthermore, the one or more grooved areas are configured to affect traction between the roller body and the tape as the tape passes over the roller body.
