Abstract
A novel coating (34) is provided on a member (24) which may be part of a mold (24). Plastic articles (10) which are made by injection molding within such a mold (24) can have a very smooth surface by replication of the surface coating (34). This allows the production of so-called rigid discs with a plastic core in place of the present day aluminum cores.
