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.
