Patent ID: 7093346

Claim:
A method for making a disk mounting hub for mounting a disk on an axial hard disk spindle in which said disk has opposite parallel faces between a disk outside diameter and a coaxial disk inside diameter defining a central opening there through, comprising: forming a rigid cylindrical hub body having a hub outside diameter disposed along a central axis; forming a cylindrical disk-mounting member disposed coaxial with said central axis at one end of said body and extending proximally with an inside diameter from said one end of said body, said inside diameter being sized to be received through said disk opening; forming a coaxial hub face extending from said hub outside diameter to said member inside diameter adjacent to said one end of said hub as a truncated conical surface of revolution symmetrical about said axis, in which said conical surface is disposed at an oblique hub face angle Ω relative to said axis; wherein said hub face angle Ω acts to minimize a disk conning angle Φ when said disk is clamped against said hub face.
