Method for maintaining concentricity of a combination of a top and bottom substrate during the assembly of a bonded storage disk

摘要

A system and method to maintain concentricity of a center hole of a top substrate and of a bottom substrate in a bonded storage disk manufacturing system. A first device holds a coaxial arrangement of a top and bottom substrate around a first arbor. A second device holding the arrangement in a coaxial arrangement around a second arbor. One of the first and second arbors is fixed to its associated device and the other is movable in response to urging from the one arbor so that the arrangement maintains concentricity.
