ABSTRACT:
Disclosed is a method of manufacturing a spindle motor using a fluid bearing. The spindle motor includes a hub having a support member for supporting a disk storage medium and a magnet, a fixed member having a coil, for holding the hub rotatably, and a fluid bearing provided between the hub and the fixed member. In this method, the hub is secured to the fixed member through the fluid bearing. This method includes a step of grinding a support surface of the support member. In this grinding step, a grinding member is applied to a part of the support member, and other part of the support member is pressurized by a pressurizing member to prevent the hub from falling down due to the pressurization by the grinding member.
