Abstract
The invention includes a disk damper containing an extended area located on the upstream side of the head stack assembly. The extended area is joined to a tail section. In the extended area, the disk damper provides a wall near the neighboring rotating disk surface that extends from the outside diameter to the inside diameter of the rotating disk surface. Experimental results have shown that this provides much more consistent dampening of disk vibrations and vibrations of a head stack assembly positioned anywhere from the inside diameter to the outside diameter. The hard disk drive including the disk damper. Using the disk damper in a hard disk drive to improve the reliability of the hard disk drive during track following. Making the hard disk drive using the disk damper, and the hard disk drive as a product of that manufacturing process.
