Abstract
Approaches to use of a squeeze air bearing for supporting and/or rotating the disks in a hard-disk drive. The squeeze bearing, whose effect is based on relative normal motion between two surfaces, is arranged adjacent to the rim of the disk to provide a bearing force at the disk rim. The squeeze bearing comprises multiple cantilevered arms with one end fixed to a support ring assembly and the other end having one or more vibrational element which, when vibrating, provides the bearing force. At least one of the vibrational elements is configured at an angle to the disk rim and which, when vibrating, provides a tangential force to rotate the disk for HDD operational purposes. Therefore, such a squeeze bearing provides an integrated solution for bearing and rotating the disk(s) of an HDD, thereby eliminating the need for a liquid-based disk spindle motor system.
