    Abstract: A golf ball that enhances flight performance is provided. A golf ball according to the present invention includes a spherical core, at least one cover member that covers the core, and a coating layer that covers the cover member configuring the outermost layer. A plurality of dimples are formed in the cover member configuring the outermost layer. The thickness of the coating layer is 5.0 μm or more. Roughness is formed on the surface of the coating layer after coating the cover member configuring the outermost layer. The maximum height Rz and the arithmetic average roughness Ra of the surface of the coating layer satisfy the relationship Rz≧Ra×6.0.

    Abstract: A golf ball has, on a surface thereof, a rugged pattern composed of a land and a large number of dimples. A method for designing the rugged pattern includes the steps of: (1) assuming a large number of circles on a surface of a phantom sphere; (2) assuming a large number of generating points 16 based on positions of the large number of circles; (3) assuming a large number of Voronoi regions 18 on the surface of the phantom sphere by a Voronoi tessellation based on the large number of generating points 16; and (4) assigning a dimple and a land to the surface of the phantom sphere based on contours of the large number of Voronoi regions 18.

    Abstract: A golf ball includes a core and a cover. A difference (FB2−FC2) between a secondary natural frequency FB2 of the golf ball and a secondary natural frequency FC2 of the core is not less than 80 Hz and not greater than 420 Hz. The golf ball having a sum (FB2+FC2) of not less than 4000 Hz is preferable. Preferably, the FC2 is not less than 1800 Hz and not greater than 2500 Hz. Preferably, the FB2 is not less than 2000 Hz and not greater than 2800 Hz. Preferably, an amount of compressive deformation Dc is 2.30 mm to 3.90 mm. Preferably, an amount of compressive deformation Db is 1.80 mm to 3.30 mm. Preferably, a thickness Tc is 0.80 mm to 2.10 mm. Preferably, a Shore D hardness Hc is not less than 52 and not greater than 65.

    Abstract: A golf ball 2 has a large number of dimples 10 on a surface thereof. Fifteen axes are assumed for a phantom sphere of the golf ball 2. 30240 points on a predetermined region of the surface of the golf ball 2 during backspin about each axis are determined. A length L1 of a perpendicular line that extends from each point to the axis is calculated. A total length L2 is calculated by summing 21 lengths L1 calculated based on 21 perpendicular lines arranged in a direction of the axis. A transformed data constellation is obtained by performing Fourier transformation on a data constellation of 1440 total lengths L2 calculated along a direction of rotation about the axis. A peak value and an order of a maximum peak of the transformed data constellation are calculated. A minimum value of 15 peak values is not less than 95 mm.
