Abstract
A tape guide in a tape cartridge for use with a tape drive includes a fixed shaft and a cylindrical sleeve positioned around the shaft. The sleeve has an inner surface and an outer surface. The inner surface of the sleeve engages the shaft such that there is friction between the sleeve and the shaft. This friction is overcome by friction between tape and the outer surface of the sleeve when the tape engages the outer surface of the sleeve causing the sleeve to rotate around the shaft as the tape moves. The friction between the tape and the outer surface of the shaft decreases below the friction between the sleeve and the shaft once the tape moves at a velocity sufficient to develop an air film between the tape and the outer surface of the sleeve causing the sleeve to cease rotation around the shaft.
