Latest Patents
Xianghui Xiao's latest patents include innovative methods for calibrating thresholds and gains in touchdown sensors. One of his patents describes a disk drive that features a head actuated over a disk with multiple tracks. This head includes a touchdown element that generates a touchdown signal, which is amplified to create an amplified touchdown signal. The invention allows for the detection of touchdown events by comparing the amplified signal to a threshold. During calibration, both the gain and threshold are adjusted to ensure optimal performance.
Another significant patent involves detecting head touchdown by computing anti-correlation in the sensor signal. This disk drive also comprises a head actuated over a disk and a dynamic fly height actuator that controls the head's position. By applying a periodic control signal to the actuator, the system generates a periodic response in the touchdown signal. The anti-correlation computed between the cycles of the signal enables the detection of the head contacting the disk.
