White Paper for Hard Disk Drive Performance Degradation Susceptibility to Acoustics ✓ Most Recent

As perpendicular magnetic recording technology has matured and areal density growth of heads and media improvements has slowed, hard disk drive (HDD) development teams have gained surface area and have increased capacity by adding disks within the same form factor. The additional space consumption usually comes at a cost to servo-mechanical design. Disks, base decks, top covers, and head stack assembly arms become thinner and limit the mechanical design options that otherwise provide robustness to external excitations that impact HDD performance.
