A multi-piece solid golf ball comprising a solid core and a cover of two inner and outer layers surrounding the core. Inserted into the center hole is a retainer to attach a stamper on the fixed-side metal mold. The segmented mapping table allows memory access to logical addresses associated with the loaded segment when the segment is loaded, rather than delaying accesses until the entire mapping table is loaded. Each claw is tapered to a straight end edge which edge is transverse to the end portion. With this configuration, the flexible substrate and the flexible display device can be enhanced by preventing property deterioration of the elements due to bending stresses. A method for generating an animal identification band by an animal management system is disclosed.
