Disk drive including surface coated disk clamp screws with reduced coefficient of friction for mitigating disk clamp movement |
摘要 |
An aspect of the invention can be regarded as a disk drive that includes a disk drive base, a disk including disk surface, and a spindle motor including a spindle motor hub including a clamping surface with disk clamp holes. The disk drive includes a disk clamp disposed upon the disk surface. The disk clamp includes a screw head interface surface and screw openings. The disk drive includes disk clamp screws each including a shaft sized and configured to respectively engage the threaded disk clamp holes respectively through the screw openings. The screws each further include a screw head having a screw head clamping surface disposed against the screw head interface surface. The screws each further include a surface coating disposed upon the screw head clamping surface. The surface coating has a static coefficient of friction less than a static coefficient of friction of the screw head.
