摘要: An apparatus and associated method for reorienting the magnetic anisotropy of magnetic recording discs. A pallet that is moveable along a path of travel is also sized to selectively hold either a first magnetic recording disc of a first size or a second magnetic recording disc of a second size different than the first size. A first processing chamber in the path of travel is adapted for forming a soft underlayer (SUL) of magnetic material with non-radially oriented magnetic anisotropy on a substrate corresponding to one of the first and second magnetic recording discs. A second processing chamber in the path of travel downstream of the first processing chamber is adapted for selectively re-orienting the SUL's magnetic anisotropy via a magnetic source emanating a first magnetic field if the substrate corresponds to the first magnetic recording disc and emanating a different second magnetic field if the substrate corresponds to the second magnetic recording disc.
