    摘要： A golf ball with a controlled moment of inertia and controlled spin rate is disclosed. The increase in moment of inertia is preferably accomplished by a reduction in the specific gravity or weight of the core, e.g., by foaming. Preferably, this reduction is less than about 15% in specific gravity or less than about 25% in weight to minimize the reduction in the coefficient of restitution of the core.

    摘要： A golf ball is disclosed that provides a softer feel, resilient core for decreased spin rate. The golf ball has a dual-layered core surrounded by a dual-layered cover. The volume of the inner layer of the dual layer core is at least about 70% of the total volume of the inner core layer and the outer core layer. The inner core has a diameter from about 1.25 inches up to about 1.55 inches. The outer core has a diameter from about 1.55 inches up to about 1.62 inches. The compression of the dual core is from about 60 to about 100. The outer core layer is constructed from materials that provide for a Shore C hardness of at least about 80. The dual-layer cover includes an inner layer having a Shore D hardness of at least about 60 and a thickness of about 0.015 inches to about 0.055 inches. The outer core layer has a Shore D hardness of about 62 or less and a thickness less than about 0.035 inches.

    摘要： A high performance golf ball having a reduced overall distance while maintaining the appearance of a high performance trajectory. The golf ball includes a combination of low CoR core and cover materials coupled with a less efficient aerodynamic dimple pattern that achieves a reduction in carry and overall distance of at least 5 yards versus a conventional golf ball, while still providing the look, sound, feel and apparent flight of a conventional golf ball. A high performance golf ball having a reduced distance is also achieved by maintaining the lift to weight ratio to be greater than 1.5 at a Reynolds number of about 205,000 and a spin rate of 2900 rpm.
