ABSTRACT:
It is an object of the present invention to provide a low-cost disk device with which the same spindle motor and clamper can be used for different types of disk device, such as a DVD drive. A clamper comprises a clamper main body and a plurality of positioning components. The clamper main body clamps a disk between itself and a spindle motor that holds and rotates the disk. The plurality of positioning components are formed on the clamper main body for the relative positioning of the clamper main body and each of the plurality of spindle motors in the radial direction.
