In Situ Sensor Based Contact Detection |
| 摘要 |
Apparatus and method for positional sensing and control. In accordance with some embodiments, a transducer is positioned adjacent a recording medium. The transducer includes a write element, a read element, a heater and a thermally responsive sensor. Power is applied to the heater to establish a selected fly height of the transducer relative to the medium. A contact event between the transducer and the medium is detected responsive to an accumulated plural count of pulses in a bias signal obtained from the thermally responsive sensor. |
