ABSTRACT:
A spindle motor includes a spindle motor hub that supports one or more disks, and has a contact area reduction portion that minimizes the area of contact between the hub and a disk when the disk is mounted to the hub. The spindle motor hub includes a hub body having a cylindrical sidewall that includes a contact section around which the disk extends and a non-contact section. The non-contact section is constituted by the contact area reduction portion. An outer diameter of the cylindrical hub body at the contact section is greater than an outer diameter of the cylindrical hub body at the contact area reduction portion of the non-contact section.
