ABSTRACT:
A hydrodynamic bearing apparatus and a method for manufacturing a hydrodynamic bearing apparatus consists of providing a shaft and rotatably fitting the shaft to a bearing. Hydrodynamic pressure generating grooves are cut on the bearing surface of either the bearing or the shaft. The bearing surface that has the hydrodynamic pressure generating grooves thereon faces another bearing surface so that the bearing and shaft rotate with respect to one another, and the bearing or the shaft that has a bearing surface having the hydrodynamic pressure generating grooves is comprised of a thick main body member and a thin sleeve fitted to the main body member. The thin sleeve is thinner and made of a softer material than the main body member, the thin sleeve is evenly deformed, and the hydrodynamic pressure generating grooves are cut on a surface of the thin sleeve.
