Abstract

A smooth homogeneous surface is provided on an alu­ minium alloy disk substrate by rotating the substrate, heat­ ing the rotating substrate with a laser beam to melt a portion of the upper surface, including any second phase defects, and polishing the melted surface after it has solidified.
