Hard Disk Drive Low Profile Disk Clamp To Tied-Shaft Motor Assembly

摘要

A hard disk drive is described, including a low-profile disk clamp to tied-shaft spindle/spindle motor assembly, in which a clamping nut is threaded onto a threaded spindle sleeve and a stationary shaft screw, or tied-shaft, penetrates through the HDD cover and into a shaft. The disk clamp may include a central opening for centering about the sleeve by way of the outer diameter of the clamping nut mating with the outer diameter of the clamp opening.
