Abstract
A circuit includes a slider, a data storage medium and a contact detection circuit electrically coupled to the slider and to the data storage medium. The contact detection circuit is configured to sense an electrical current indicative of contact between the slider and the data storage medium and responsively provide a contact detection output. The electrical current is produced without the application of a separate voltage between the slider and the data storage medium.
