ABSTRACT:
A method and apparatus is disclosed for permitting a plurality of substrates to be positioned within a magnetic field unique to each substrate so that the plurality of substrates may be placed in a vacuum chamber and concurrently coated with a thin film. A magnetic field unique to and associated with each substrate may be oriented so that all substrates have a uniform magnetic field and magnetic orientation. Alternatively, the magnetic field and orientation of each substrate may be individually tailored to produce a different magnetic characteristic for each substrates.
