Contact and Temperature Rise of Thermal Flying Height Control Sliders in Hard Disk Drives
نویسندگان
چکیده
Contact behavior of thermal flying height control sliders and interfacial temperature rise upon head disk contact is investigated utilizing the resistance change of the read and write element. To achieve contact, the heater element of a TFC slider is energized with constant and square wave input profiles. To estimate the temperature rise during head disk contact, the resistance change of the read and write head is investigated as a function of heater power. Auxiliary calibration measurements were carried out to measure the resistance for both the read and the write head as a function of temperature.

Numerical simulation of thermal flying height control sliders in heat-assisted magnetic recording
Heat assisted magnetic recording (HAMR) is one of the most promising techniques to extend the recording density in hard disk drives beyond 1 Tb/in. Although the diameter of the spot on the disk that is heated by the laser beam is very small, on the order of nanometers, high local temperatures on the disk and the heat dissipated in the slider during the light delivery process can cause thermal d...

In recent years, thermal actuated flying height control has been implemented in Hard Disk Drives (HDD) to reduce the effect of flying height variations due to manufacturing tolerances or write current introduced pole tip protrusion (Fig. 1). A stable low flying height is necessary to achieve low bit error rates (BER) [1]. Thermal flying height control is used in a “static manner” in current dis...
