Beschreibung
Zusammenfassung:	The invention relates to a fluid dynamic bearing pattern that is disposed on at least one bearing surface of the two bearing parts of a fluid dynamic bearing that are moveable with respect to each other along a direction of movement. The bearing pattern comprises two related grooved sections, each section extending at an acute angle with respect to the direction of movement and exerting a defined pumping effect on the bearing fluid found in the bearing when the bearing parts move with respect to each other. According to the invention, the first section is disposed at an angle α and the second section at an angle with respect to the direction of movement, the two angles varying in size.
