Abstract
Generally disclosed is a golf ball having a core and a cover layer. The cover layer includes areas that are hard corresponding to the dimples, and areas that are soft corresponding to the land between the dimples. The cover layer may be selectively treated, such as by heating, to achieve a difference in hardness using a single cover layer material. Alternatively, the cover layer may be selectively coated with a coating material having a different hardness. As a result of the arrangement of the hard dimples and the soft land, the golf ball achieves reduced spin, and greater distances, when struck with a larger force (such as during a dive) while also achieving increased spin, and better control, when struck with a smaller force (such as during a chip).
