A method for casting a reactive material PVD target, as well as targets thus obtained and a mold for casting. The method includes providing a mold defining an opening, placing a reactive material ingot into a reservoir () proximate the mold, forming a vacuum and melting the reactive material in the reservoir, heating the mold to above a casting temperature and forming a vacuum therein, introducing molten reactive material from the reservoir into the opening and cooling the mold to form the PVD target.

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.
