摘要： A thread-wound golf ball has a wound core consisting of a center with a diameter of 29-37 mm and a rubber thread layer with a thickness of 1.0-2.5 mm. A cover enclosing the wound core is of two-layer construction comprising a relatively soft inner cover layer and a relatively hard outer cover layer having a Shore D hardness of 55-65. The inner and outer cover layers combined have a thickness of 2.0-5.0 mm. This construction gives the golf ball an excellent scuff resistance when hit with an iron club, as well as an improved spin, feel, and flight performance upon a full shot with a driver.

摘要： The invention provides a multi-piece solid golf ball having a solid core encased by a cover of one, two or more layers, which ball has specific hardness relationships among various areas on a core cross-section obtained by cutting the solid core in half. The golf ball has both a reduced spin rate and a good initial velocity on shots, particularly when struck in a high head-speed range, and thus is able to achieve an increased distance. A good feel on impact can also be obtained.

摘要： The invention provides a golf ball having a solid core, a cover of at least one layer, and a plurality of dimples on a surface of an outermost layer of the cover. The dimples have a volume ratio (VR) of at least 1.6%. The ball has an initial velocity, as measured using an initial velocity measuring apparatus of the same type as a USGA drum rotation-type initial velocity instrument, which is at least 77 m/s, and has a ratio of total distance traveled when struck at a head speed of 54 m/s to total distance traveled when struck at a head speed of 35 m/s (HS54/HS35) of from 1.30 to 1.50. This golf ball is able to substantially reduce the distance traveled by the ball when struck at a high head speed, while at the same time holding down the decrease in distance when struck at a low head speed.
