Abstract
A spindle for providing precise radial location of a disk includes a spindle having a key that extends from one end thereof. The disk includes a hub having a shape that is similar to that of the spindle with a key notch disposed on the peripheral edge thereof that is shaped similar to that of the key in the spindle. The key has two surfaces that come together at an angle to an apex, which apex extends downward away from the spindle and radially outward. The surfaces of the key notch on the hub are longer than that of the key, such that the surfaces of the key can mate with the surfaces of the key notch and slide therealong, such that the spindle is maintained in the center of the hub.
