    摘要： A spindle motor assembly includes a spindle motor, a disk for storing data, the disk being installed on the spindle motor, and a disk clamp for fixing the disk to the spindle motor. The disk clamp includes a hollow formed in a central portion thereof, a coupling portion formed around an external circumference of the hollow and including a plurality of screw insertion holes into which clamp fastening screws to be coupled to the spindle motor are inserted, and a pressing portion formed around an external circumference of the coupling portion to press the disk. The coupling portion includes a first region and a second region that are asymmetrical with respect to each other, the plurality of screw insertion holes are formed in the first region only, and a thickness extension portion or a through hole is formed in at least a portion of the second region.

    摘要： A hard disk drive (HDD) includes a spindle motor, an actuator, a static eccentricity sensor, a monitor and a central controller. The spindle motor includes a rotary body and a static body adapted to support the rotary body, where the spindle motor is adapted to rotate a disk. The actuator is adapted to move a read/write head over the disk. The static eccentricity sensor is adapted to measure static eccentricity associated with the rotary body. The monitor is adapted to monitor the measured static eccentricity and generate a free-fall signal when the monitor determines that the HDD is in a free-fall state. The central controller is adapted to initiate an unloading/parking operation for the read/write head in response to the free-fall signal.
