Support device for vibration and noise reduction of the hard disk drive and external shock mitigation

摘要

The present invention relates to a supporting device for external vibration or shock of a hard disk drive.;The hard disk drive includes a disk 2 rotating at high speed by an internal spindle motor 1, a head 5 having an actuator 4 and a magnetic head 5 for recording or reading data recorded on the track of the disk. A pivot shaft 3 for supporting a shaft of the spindle motor 1 and a head pickup to reduce noises and external vibrations or shocks to the hard disk drive installed to be rotated around the pivot shaft 3, A plate 13 as a support device is mounted on the spindle motor shaft and the pivot shaft 3 and fixed to the base body 20 so as to be fixed to the spindle motor shaft 20, And a damper (14) for absorbing vibration is attached so as to reduce vibrations and impacts.
