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.

A method of manufacturing a spindle motor for disk storage device that includes a hub having a support member for supporting a disk storage medium and a magnet, and a fixed member, having a coil, for supporting said hub in a rotatable manner, said method comprising:
- a step of securing said hub to said fixed member through a fluid bearing;
- and
- a step of grinding a surface of said support member, thereby forming a support surface for supporting the disk storage medium, while rotating said hub,
- wherein said grinding step is a step of applying a grinding member to a part of said support member and also pressuring an other part of said support member with a pressurizing member so as to prevent tilting of said hub due to the pressurization by said grinding member.
