Abstract
In order to assess the tribological behavior of a head-disk interface, rigo rous test procedures involving time-consuming contact-start-stop tests are used. Considering the high rate at which new hard disk models have to be in troduced to the market, there is a strong motivation in the industry to be able to reduce this evaluation time and cost. In this work, feasible method s that can be used to accelerate the slider-disk tribological assessment of a hard disk drive are presented. A drag test and low ambient pressure test s were performed to induce more contact between the slider and the disk. Th ese test methods were compared with normal contact-start-stop test results with respect to stiction or friction, bump wear, and slider contamination. Finally, the degree of accelerated wear rate of these tests was analyzed ba sed on Archard's wear equation. It is expected that results presented in th is work can be used as a screening method for slider-disk compatibility fro m the tribological point of view.
