Abstract

According to the present invention, a blank of an aluminum alloy is partially cut so as to form several disks maintained in the blank by portions of the remaining uncut aluminum. This results in the disks being supported in the blank during formation of the thin films, yet easily separated from the blank into individual disks after the thin films have been deposited. Therefore, multiple disks can be processed during a single manufacturing step.
