Golf ball
First Claim
1. A golf ball comprising:
- a core comprised of an inner core and an outer core, a thin dense layer disposed around the outer core and a cover disposed about the thin dense layer;
wherein said thin dense layer has a thickness between about 0.001 and about 0.050 inches and a specific gravity of greater than 1.8;
wherein said inner core comprises a specific-gravity-reducing agent, has a diameter from about 0.50 inch to about 1.54 inches and has a specific gravity of less than 0.9, andwherein the outer core has thickness of about 0.05 inch to about 0.575 inch, has a specific gravity of about 0.5 to about 1.05 and is substantially free of fillers.

Abstract
A high CoR golf ball having predetermined moment of inertia is provided. A portion of the golf ball preferably contains substantially no filler, which contributes to the increased resilience of the ball. In accordance to one aspect of the invention, the portion with substantially no filler is an intermediate layer of the ball, and preferably is the outer core layer of the ball. The remaining portions of the ball preferably contribute to the moment of inertia of the ball. To craft a low moment of inertia ball, the innermost core should have a high specific gravity. Additionally, the outermost layers of the ball may have a low specific gravity. Conversely, to craft a high moment of inertia ball, the ball should have a thin dense layer positioned radially outward from its centroid radius. Additionally, the innermost core may have a low specific gravity. To craft a mid range moment of inertia ball, the ball may comprise a high specific gravity inner core and a thin dense layer. Preferably, the portion with substantially no filler is relatively larger than other portions of the ball.
