Ramp load/unload (L/UL) technology becomes core technology in mobile hard disk drive (HDD) because it enables higher areal density and stronger shock robustness. However, ramp L/UL has some instability because of the structural limit that a head should repeatedly move between a ramp and a disk. Among much instability, the slider-disk contact generated during L/UL process mainly affects the drive reliability. In particular, the slider-disk contact during the loading process has a critical effect… CONTINUE READING
