Disks 15 in disk drive 10 (Fig. 1) build up a static charge as they rotate because of the polymer coating on the disk surfaces. Thus even if the head arm suspension 20 (Fig. 2) is grounded, the disk 15 becomes charged. Particulate contaminants in the disk enclosure are attracted to charged surfaces and tend to buildup between the head and disk. This can lead to a crash between the heads and disks.
