Patent ID: 7904918

Claim:
A disk device comprising: a clamper; and a spindle motor, the clamper including a clamper main body configured to clamp a disk between the clamper and the spindle motor, and a first positioning component disposed on the clamper main body, and a second positioning component disposed on the clamper main body, the first and second positioning components configured to relatively position the clamper main body and the spindle motor in a radial direction of the clamper main body and the spindle motor, the first positioning component including a conical portion; the spindle motor including a disk holding component having a main body that holds the disk between the spindle motor and the clamper, a first positioning component being disposed on the main body, a second positioning component being disposed on the main body, and a motor main body fixed to the disk holding component and being configured to rotationally drive the disk holding component and the disk, the first positioning component including a conical portion, wherein the conical portion of the first positioning component of the clamper main body engages the conical portion of the first positioning component of the disk holding component so as to position the clamper main body and the spindle motor in the radial direction of the clamper main body and the spindle motor when a disk is not positioned in the clamper, and when a disk is positioned in the clamper and in a play state, the first positioning component of the clamper main body is spaced from the first positioning component of the disk holding component, and the second positioning component of the clamper main body engages a first side of the disk and the second positioning component of the spindle motor engages a second side of the disk.
