Abstract
The dynamic load head-disk interface durability is experimentally investigated using 50 percent TPC sliders and super-smooth disks. Severe head-disk contact conditions are applied and disk-synchronized head loading motions are performed in order to see the effect of repeated dynamic load head-disk contacts. Readback signals are recorded and analyzed, and the disk surfaces of the head-disk contact area are examined after 100,000 repeated contacts. The results are compared with those of our previous study. We find that the dynamic load head-disk interface durability of 50 percent TPC sliders and polished disks is superior to that of 70 percent taper-flat sliders and textured disks, and the experimental results suggest that better dynamic load head-disk interface reliability can be achieved with good head-loading velocity control, even though head-disk contact may occur during loading.
