The touch-down test is widely used to calibrate the flying-height (FH) of sliders by gently contacting the disk with the thermal protrusion of thermal FH control (TFC) sliders. However, the dynamic instability of TFC slider during the touch-down process may significantly affect the contact detection and the FH calibration, and therefore, hinders further reduction of the FH of TFC sliders. This paper...
The touch-down test is widely used to calibrate the flying-height (FH) of sliders by gently contacting the disk with the thermal protrusion of thermal FH control (TFC) sliders. However, the dynamic instability of TFC slider during the touch-down may significantly affect the contact detection and FH calibration. This paper highlights the nonlinear dynamics perspectives on the instability of TFC sliders...
