ABSTRACT:
A coating comprising a urethane resin as a base, and at least polyurethane particles and fluororesin powder is formed on a surface of a member that is, or can be, contacted with an optical disk in an optical disk apparatus. The coating can prevent the optical disk, i.e., a CD, a DVD, etc., from damaging, even if the optical disk is contacted with a tray or an objective lens.
