For successful operation of tape drives, the friction experienced at the head/tape interface should be minimal for ease of starting and lower head wear. A simple and versatile tester is needed to measure friction in a simulated environment. The tester should be easy to set up, operate and collect data. Furthermore, it should provide complete flexibility to vary and to measure the following parameters: wrap angle, tension, sliding speed, head (simulated by a ferrite rod) radius, ambient temperature, and humidity. Some flexibility is needed to be able to run tests in extreme and accelerated conditions.
