  • Contact detection using laser modulation
    Patent number: 9202499
    Abstract: An apparatus is arranged to detect contact between an air bearing surface of a transducer and a medium using a modulated thermal sensor signal. A laser source produces modulated laser light. A thermal sensor is disposed at or near the air bearing surface and is subject to cyclic heating by the modulated laser light. The thermal sensor is configured to produce the modulated sensor signal in response to the cyclic heating.
    Type: Grant
