Abstract
Methods of operating a recording media press system are described. The method may include clamping, with a plurality of first tabs, an outer perimeter portion of a first embossing foil to a first die of a die press and clamping with a plurality of second tabs, an outer perimeter portion of a second embossing foil to a second die of the press. The method may also include receiving a magnetic recording disk in the die press, interleaving the plurality of first tabs with the plurality of second tabs to close the die press around the magnetic recording disk, and pressing the first and second embossing foils against the recording media disk to emboss a front and backside of the recording disk with a discrete track recording pattern.
