ABSTRACT:
An apparatus for laser texturing the inner annular region of a substrate is described. The apparatus includes a Bernoulli holder for supporting the disc at a fixed distance from a support face in the holder, and a laser beam for directing a pulsed laser beam on the substrate's inner annular region. Also included is an optical assembly for varying the position of such a spot on such inner annular surface region of the substrate.
