ABSTRACT:
A process for generating a capacitive servo pattern on a magnetic storage disk, comprising the steps of: (1) coating the disk with a solution of noble metal compound to form a film of the compound on the disk, (2) exposing said film to radiation through a mask to generate an image on the film, and (3) plating the disk on the areas exposed to radiation.
