SPINDLE MOTOR AND CLAMPER

摘要

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 100 comprises a clamper main body 104 and a plurality of positioning components. The clamper main body 100 clamps a disk 10 between itself and a spindle motor 210, 220, or 230 that holds and rotates the disk 10. The plurality of positioning components are formed on the clamper main body 104 for the relative positioning of the clamper main body 104 and each of the plurality of spindle motors 210, 220, and 230 in the radial direction.
