Abstract
A data storage device may have increased signal-to-noise ratio contact detection by employing a transducing head assembly separated from a data storage medium by an air bearing with the transducing head assembly receiving an alternating current as directed from a controller. The alternating current can be configured to induce random transducing head motion when the air bearing has a greater than zero size and a cyclical transducing head motion when the air bearing has a zero size.
