Abstract:
An apparatus for reorienting the magnetic anisotropy of the soft underlay of a magnetic recording disc having a diameter less than that of the pallet, which operates by first heating the disc, then using a heat transfer plate to cool the disc in the presence of a magnetic field having a radial direction emanating from the center of the magnetic recording disc.
