Abstract

A fluid dynamic bearing has two relatively movable bearing surfaces. One of the bearing surfaces defines a first groove zone and a second groove zone. First and second grooves are formed at the first groove zone. Third and fourth grooves are formed at the second groove zone. Each first groove communicates with one adjacent second groove at the edge of the first groove zone that is away from the second groove zone. Each third groove communicates with one adjacent fourth groove at the edge of the second groove zone that is away from the first groove zone.
