Abstract
An apparatus includes a slider of a magnetic recording transducer comprising a plurality of electrical bond pads. A component is coupled to a pair of the electrical bond pads. A sensor is coupled to the pair of the electrical bond pads in parallel with the component. The sensor is configured to sense for one or more of thermal asperities of a magnetic recording medium, voids of the medium, spacing changes between the slider and the medium, and contact between the slider and the medium. The sensor is configured to be rendered non-functional in response to the sensor receiving a predetermined signal. The component is configured to remain operable after the sensor is rendered non-functional.
