Abstract
A corner belt guide roller for use in a belt driven tape cartridge is disclosed. The roller controls drag on the driving belt to maintain magnetic tape tension and reduce variability in the cartridge operation. The guide roller is mounted on a pivot pin through an inner cylindrical surface. The inner cylindrical surface has an oriented controlled texture including axial splines. This enables the guide roller to have controlled friction with its pivot pin, and provide a predetermined constant amount of drag to the driving belt to improve the consistency of the tape cartridge operation.
