Abstract
An apparatus, system, and method are disclosed for determining brush contact with a magnetic head. A digitally generated signal is provided in a system and a first gain constant is adjusted without the brush in contact with the magnetic head until the signal achieves unity gain. A second gain constant is adjusted with the brush in contact with the magnetic head until the signal once again achieves unity gain. The difference between the first and second gain constants is calculated. If the difference satisfies a predetermined threshold, a monitoring message is provided indicating insufficient contact between the brush and the magnetic head. The message may serve to warn the user that the brush arm assembly may be inoperative or a failure message indicating that the entire brush assembly needs to be replaced.
