ABSTRACT:
A disk device is presented that includes a drive motor which has a rotatable hub fitted with a recording medium and rotates the recording medium, and a disk-shaped clamper attached to the hub to hold the recording medium. The clamper has a center aperture formed on a central axis of rotation of the drive motor and at least one positioning hole eccentric to the central axis of rotation. The clamper is fixed to the hub by a fixing screw driven into the hub through the center aperture. The hub has a support surface opposed to the clamper and an annular engaging groove formed in the support surface to be coaxial with the central axis of rotation and opposed to the positioning hole, the engaging groove being configured to be engaged with a fixing pin which is passed through the positioning hole.
