Patent ID: 7757247

Claim:
A small form factor optical/magnetic disk comprising: an integrated metal hub comprising: a circular upper metal hub coupled to a disk plate using an epoxy; and a circular lower metal hub coupled to a disk plate using the epoxy, wherein the lower metal hub is integrally formed with and disposed under the upper metal hub, and has a smaller diameter than the upper metal hub, wherein a central hole is formed in and passes through central portions of the upper and lower metal hubs, wherein the integrated metal hub has an overall thickness; an intermediate body coupled to an outer-surface of the lower metal hub using the epoxy; and the disk plate comprising: a through-hole formed in a central portion that passes entirely through the disk plate such that the through-hole has a depth substantially equal to a depth of the disk plate, and a recess that is formed around the through-hole and allows the upper metal hub to be mounted therein, wherein the depth of the through-hole of the disk plate is substantially equal to the overall thickness of the integrated metal hub such that top and all bottom surfaces of the integrated metal hub and of the disk plate are substantially flush with each other when the integrated metal hub is nested within the through-hole of the disk plate wherein the overall thickness of the integrated metal hub is equal to that of the disk plate such that the upper and lower surfaces of the integrated metal hub are coplanar with corresponding upper and lower surfaces of the disk plate.
