A Comparative Experimental Study on Head-Disk Touch-Down Detectability Based on Off-Track Vibration

To further increase the hard-disk drive’s areal density, the head-disk spacing needs to be reduced to sub 1 nm and it requires accurately detect the head-disk touch down (TD). The off-track-vibration-based TD detection methods are widely applied in current hard-disk drive (HDD) for head-disk TD de...
