    摘要: A fluid dynamic bearing has a shaft (11) fitted in a sleeve (12) for rotation, with a fluid filled therebetween. The shaft (11) and/or sleeve (12) is formed with a pattern consisting of grooves (111g) and lands for generating a pressure distribution in the fluid and then covered with a diamond-like carbon film (11c) over the surface of the grooves and the surface of the lands.
