摘要： Vibration of a transducer slider can be used during slider fly height calibration to detect contact of the transducer slider with a disc surface. Amplification of the vibration may cause the transducer slider to tap the disc surface rather than drag across the disc surface when detecting contact with the disc surface. Amplification may be achieved by applying an in-phase AC signal to the transducer slider at the same frequency as the vibration of the slider. Reduced contact between the slider and the disc surface reduces wear on and the possibility of damage to the transducer slider and/or the disc surface. Once the fly height of the transducer slider is calibrated, the AC signal may be shifted out-of-phase with the slider vibration to dampen the slider vibration.
摘要翻译：可以在滑块飞行高度校准期间使用传感器滑块的振动，以检测传感器滑块与光盘表面的接触。当检测到与盘表面的接触时，振动的扩大可能导致换能器滑块敲击盘表面而不是拖过盘表面。可以通过以与滑块的振动相同的频率向换能器滑块施加同相AC信号来实现放大。滑块和盘表面之间的减少的接触减少了传感器滑块和/或盘表面损坏的可能性。一旦传感器滑块的飞行高度被校准，AC信号可能会与滑块振动异相移动，以抑制滑块的振动。
