In order to realize ultra-low flying height, magnetic spacing variations due to manufacturing tolerances, environmental variations, and write-induced thermal protrusion need to be reduced. To decrease the flying height, we have developed a thermal flying-height control (TFC) slider that carries a micro-thermal actuator. Using the device, the magnetic spacing of these sliders can be controlled in-situ during operation of the drive. First prototype had shown insufficient characteristics when evaluated at a component-level prototype. Therefore, the purpose of this research is to develop an improved TFC slider and verify its drive level feasibility. After analytical design by simulation of heat transfer and thermal deformation, prototype of TFC device was fabricated. Spin stand evaluation showed sufficient actuator characteristics that met the requirements leading to the development of drives with controllable flyng height sliders. Evaluation of HDD with TFC slider showed a remarkable effectiveness of TFC slider in reducing the magnetic spacing.
