<P>PROBLEM TO BE SOLVED: To improve a prior art of a golf ball by further adding alternatives of golf balls affecting flying, touch, and performance of a ball. <P>SOLUTION: A golf ball may include a first pole, a second pole, and a seam disposed between the first and second poles. On a surface of the ball, a dimple is formed as a pattern including a plurality of repetitive sectors around each pole of the ball. One half sector of the ball and the other half sector of the ball are shifted in a rotation direction with the seam as a boundary. Further, each separate sector includes a symmetric line, where a dimple pattern of one half sector forms a mirror image of the other half, with the symmetric line as a boundary. Further, various different dimple types may be disposed on the surface of the golf ball, for example within the above sector. Further another aspect provided relates to distinctive features of various layers of a multi-piece golf ball, and a method of manufacturing a golf ball having at least some of the distinctive features described above. <P>COPYRIGHT: (C)2012,JPO&INPIT |
