Abstract
An apparatus and system for improving the contact between the heads of a disk drive and the storage media of the disk by improving disk stability. The apparatus comprises a disk having a disk stability pattern disposed proximate a center region of the disk. The disk stability pattern improves disk stability by reducing vibration modes in the spinning disk, thereby minimizing the formation of standing waves in the spinning disk media, and by improving disk compliance, thereby minimizing disk anisotropic curl and tilt.
