ABSTRACT:
An apparatus and method for aligning a disk with an imprinting surface are described. In one embodiment, the apparatus has a die which includes an air-bearing mandrel having a tapered nose to engage an ID of the disk, a circular imprinting surface having a centerline concentric with the air-bearing mandrel, and an air-bearing cavity to position the disk. The axial movement of the top die towards the bottom die guides the ID of the disk into coincident alignment with the centerline of the top die.
