Friction Study

Voltage assisted wear at the head and the disk interface is investigated with the motive of understanding the head overcoat wear processes. In this work, we report the quantitative analysis of voltage assisted wear on head carbon overcoat at high sliding speed interfaces. We found that voltage assisted TFC head wear acts asymmetrically at the interface with positive voltage leading to high wear. We quantitatively analyzed the interface using a strain gauge based friction measurement.

Friction Study

The dynamic friction and wear at the head and the disk interface is investigated with the motive of understanding the head overcoat wear process associated with physical contact between the head and the disk. In this work, the results from systematic experiments under overpush conditions are presented. Various regimes of head wear are identified based on the individual wear rate of the participating overcoat layers. A strain gauge based friction measurement is used to extract the friction coefficient and the adhering shear strength between the head and the disk.
