History of the Golf Ball
The characteristics of golf balls are strictly
governed by rules. In addition to weight and
size, these rules determine maximum initial
velocity, total distance, and other
characteristics. So, what appears to be just a
small round object is in fact the product of
many leading-edge technologies. Ball structures
break down broadly into two categories: wound
balls, which are the conventional ball; and the
solid ball, which made its appearance in the
1980s. Ball structure can be broadly divided
into two categories: wound balls, which are a
direct descendant of the Hasket ball, invented
in 1898; and solid balls, which evolved from
one-piece ball that was invented in 1966. Until
recently, the general opinion among golfers has
been that solid balls produced a hard feel at
impact, and that they offered poor spin control
performance. However, with the development of
balls made of urethane resins, the ratio of
professionals using solid balls at the 2000 US
Open reached 30 percent. As such examples
indicate, balls are being improved in ways that
increasingly meet golfers' needs. Approximately
1,500 kinds of balls have been approved by the
R&A and USGA. In addition to these, a large
number of unapproved balls are available on the
market today. Within this universe, golfers will
find balls that have made this kind of progress.
The message is that golfers should take the time
to try new balls, rather than say "I'll play the
same ball because it's the one I've used
before." By doing so, they find themselves
discovering balls that more closely fit their
style of play.

Golf Ball Types
Wound balls
These are balls in which rubber thread is wound
around one of two kinds of cores: a liquid
center, where the core is liquid-filled; or a
solid center, in which the core is made of
synthetic rubber. This is then wrapped in either
a balata or surlyn cover. Ball characteristics
differ depending on the way in which the
materials for the center and cover are combined.
Generally speaking, wound balls excel in spin
performance, but fall short in terms of distance
and durability. They are also sensitive to
temperatures, losing distance as temperatures
fall (below 20?C).
One-piece balls
These are balls made of a single,
high-restitution synthetic rubber. Because these
balls deform to a large degree at impact, they
lose a great deal of the energy required for
carry and consequently offer less distance than
balls built with different structures. However,
because they are extremely durable and
economical, they continue to be manufactured
today, primarily for driving-range use.
Two-piece balls
These are dual-structure balls in which a
high-restitution core is wrapped in a cover.
This configuration enables the energy at impact
to be transferred efficiently to the ball in
flight. Because the cover itself is made of a
high-restitution material, these balls generate
excellent distance. Recently, manufacturers have
been introducing two-piece balls with a
?soft-feel,? which is conducive to greater
control.
Multi-layer balls (3-piece balls)
These are multi-layer balls in which the core
material is wrapped in multiple covers. As a
result of the latest advances in technology,
manufacturers are now able to flexibly combine
materials, degrees of hardness, specific
gravity, and so on, in ways that enhance a
variety of performance features. The result has
been such path-breaking advances as balls that
can compensate for slightly missed hits.
