Abstract
A golf ball is marked by directing laser light to a selected surface portion of the ball, thereby causing the exposed surface layer portion to change its color. The discolored portion forms an identification mark on the ball surface. The mark is durable and aesthetically attractive while the ball maintains dimensional precision.
