SAMSUNG HARD DISK DRIVE
<< Major components of HDD >>
HDD is formed by major components as follows: Base, Cover, ARM(E-Block), Latch, Crash Stop,
Pivot Bearing, Breather Filter, Window Clock, Window Push Pin, Jump Pin, Spindle Motor,
Disk-damper, Magnetic Head, Magnetic Disk, PCBA
Base
Base could be a basic frames for HDD assembly. Spindle motor, ARM, VCM, cover and PCBA
are assembled on it, and other components are sub-assembled on those configuration.
ARM and Spindle motor assembled to Head and Disk each in advance,then those are assembled
on Base. If base could be effected by external and internal vibration (spindle motor
& actuator's fake vibration), relative displacement occurred between head and disk so to
reduce this effect to PES(Position Error Signal) and data signal, shape design concerned
mode shaping should be needed.
Cover
Cover protect HDD components from the exterior impact and play role of sealing to cut off
particle and moisture which could be a fatal factor to head and disk. Cover is also designed
in consideration of noise and vibration effect.
ARM (E-block)
ARM is assembled HGA and VCM coil back and forth and it is connected to pivot axis pivot
bearing. When VCM coil generate torque due to electromagnetic force of VCM, ARM swing around
pivot and play a role of carriage so as head may access to information side of disk.
Inertia: It is the best way to shorten data access time that shows how fast head can
reach to the proper point on of HDD efficiency, is minimizing ARM's weight to decrease inertia.
And then to decrease weight of ARM, it'll be composed low density materials and reduce ARM's
size within safety allowed when designed.
Unbalance: If the center of gravity for ARM isn't the same with that of pivot center,
unbalance occur and it caused ARM to torque.
And acceleration might affect on unbalance mass in condition impact or vibration are given
from the exterior. In case of magnetic latch, this unbalance could be a reason that latch
released. Therefore shape simulation of ARM should be designed lest the center of gravity
should go off center of revolving.
Latch
When power HDD off, spindle motor stop spinning and park at parking zone automatically
according to the order systemized. By that time if head is given any impact or vibration
from the exterior, head invade data zone clung to disk. And then data damaged consequently,
Latch solve the problem above as maintain the regular distance of ARM.

Compared with disk failure,head related failure occur in particular HD(head) from the first
cylinder and this is occurred continuously.(it is occurred in two more heads)
If failure is continuous, we are confused if it is head failure or disk failure. At this time
read the edge of cylinder again then it is head failure if error still be continuous at the
particular head and disk failure in sporadic case. And failure occurred with changing cylinder
and head continuously, it is called assembly failure in inner HDA or caused from other problem.
