The invention relates to a hydrodynamic bearing system, particularly for a spindle motor, having a shaft, a thrust plate connected to the shaft and a bearing sleeve sealed at one end by a cover plate, the bearing sleeve enclosing the shaft and the thrust plate with a slight spacing forming a bearing gap filled with a lubricant, at least one of the bearing surfaces of the shaft and the bearing sleeve as well as the thrust plate and the cover plate interacting with each other being provided with a surface structure. The distinctive feature of the invention is that a bearing surface formed between the thrust plate and the bearing sleeve is provided with a herringbone-like surface pattern and a bearing surface formed between the thrust plate and the cover plate is provided with a grooved spiral shaped surface structure.
