Patent ID: 8208238

Claim:
An apparatus for reorienting the magnetic anisotropy of magnetic recording discs, comprising: a single disc deposition system comprising: a sputtering chamber and a circular static sputter target configured for depositing magnetic material on a surface of a disc substrate having a first form-factor, such that a magnetic anisotropy of the magnetic material on the disc surface tends to be radially oriented; and the sputtering chamber adapted to deposit magnetic material concurrently on a surface of each of a plurality of magnetic recording discs having a second form-factor smaller than the first form-factor, such that a magnetic anisotropy of the magnetic material on the surface of each of the plurality of magnetic recording discs having the second form-factor has little radial orientation; a pallet sized to hold the disc substrate having the first form-factor, the pallet adapted to hold the plurality of magnetic recording discs having the second form-factor; a plurality of heat transfer plates, the plurality of heat transfer plates including a contacting surface; and a plurality of magnetic sources adjacent to at least a portion of the plurality of heat transfer plates, wherein the magnetic sources individually have a magnetic center and provide a magnetic field having a radial direction emanating from the magnetic center, wherein each of the heat transfer plate is configured to produce a radial magnetic pattern in a soft underlayer of one of the plurality of magnetic recording discs having the second form-factor.
