  • Patent number: 7808745
    Abstract: A hard disk drive includes a base, a head stack assembly (HSA) that is mounted to the base so as to be rotatable relative to the base, a voice coil motor (VCM) block that has an upper section and a lower section respectively disposed above and below a voice coil support of the HSA, and a crash stopper that limits the rotation of the HSA at the voice coil support. The upper section of the VCM block has a through-hole through which the crash stopper extends into a space between the upper and lower sections of the VCM block. The lower section of the VCM block has a groove in which the crash stopper is received. The hard disk drive can be assembled in a top down manner to allow the assembly process to be fully automated.

  • Patent number: 7701663
    Abstract: A hard disk drive includes a base including a plurality of internal parts related to reading and writing of information. The hard disk drive also includes a cover which shields an upper surface of the base. The hard disk drive also includes a ground rib which provides at least a partial contact area between the upper surface of the base and a lower surface of the cover and which connects the base and cover at a predetermined position. The hard disk drive also includes a plurality of screws which couple the cover to the base by passing through the ground rib.

  • Patent number: 7477480
    Abstract: A disk spacer interposed between a plurality of disks that are rotatably installed on a spindle motor and has a ring shape to maintain an interval between the disks. The center of an inner circle defined by an inner circumferential surface of the disk spacer is not congruous with the center of an outer circle defined by an outer circumferential surface thereof to produce mass eccentricity.

  • Patent number: 7327530
    Abstract: A hard disk drive (HDD) having a disk damper and a disk protector. The HDD includes a base member, a spindle motor installed on the base member, a plurality of data storage disks mounted on the spindle motor, an actuator pivotably installed on the base member and moving a read/write head to specified positions over the disks, a disk damper disposed between adjacent disks of the plurality of disks and reducing vibrations of the disks, and a disk protector projecting by a specified height toward the disks form positions of top and bottom surfaces of the disk damper to correspond to outer edges of the disks where data is not recorded. Accordingly, if the disks are deflected due to an external shock, only the outer edges of the disks contact the disk protector, thereby preventing data recording surfaces of the disks from being damaged.
