<< 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,
Actuator, Magnetic Head, Magnetic Disk, PCBA

① 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.

② 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.

③ 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

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

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.

④ 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.

: It is the best way to shorten data access time that shows how fast head can

: If the center of gravity for ARM isn't the same with that of pivot center,

⑤ Crash Stop

Crash stop is made of elastic material and weaken a impact of actuator in emergency condition,
head getting out of data zone when it move to parking zone or seek.

⑥ Pivot Bearing

Pivot bearing is a roll bearing fixed the center of gyration of ARM. Inner Race is fixed by
screw after being connected to Base pivot and outer Race is fixed by retaining ring after
being connected by ARM's hole and make the ARM's revolving movement actively.

⑦ Breather Filter

In the interior of HDD, air flow is formed by the spinning disk in high speed and pressure
distribution occurred. This pressure is lower than atmospheric pressure of the exterior of
HDD and due to this, the outside air inflow into the interior caused contamination.
Breather filter fixed in inflow plug induce clean air and help air circulation.

⑧ Window Clock

Head must know the data's location information to access data on disk. Servo write is
a process of recording information disk. To record information, we make hole that head
for servo write can enter the interior of HDD and this hole is window clock.
This hole is closed with sealing label after done servo writing, be careful not to be
occurred inner contamination due to label's injury.

⑨ Window Push Pin

Head should be controlled to move on disk at a regular track pitch interval rate during
servo writing. ARM is torqued by VCM continuously and was controlled each track's moving
using push pin. Window push pin is a hole for this, the pin could enter interiorofHDA
and be careful contamination caused by label's injury because this hole is closed by sealing
label after done servo writing.

⑩ Jump Pin

During installing, HDD need setting of pin organization in the next according to
the drive running mode: master drive in single system, master drive in dual system,
slave drive in dual system.

⑪ Spindle Motor

Spindle motor is a sort of small motor which can change electric energy to mechanical energy
utilizing for magnetic field. When the current of stator's coil formed by electromagnet
is on, magnetic power occur between stator and rotator. (repeal occur between same pole and
attract occur in case of different pole) This power can make rotator revolve and we should
keep on changing the magnetic pole of the stator to maintain rotate at regular speed.
To progress this function, we deduct rotation speed and circuit for controlling needed.
It is possible to control the current flow and time interval with Hall element and MR

element (these are sensitive to voltage change). The magnetic disk of hard disk is running

by DC Brushless direct drive motor directly. Brush has long life and high reliability
because it doesn't have belt. Recently we use flat motor to be adopted to the request of
minimizing. The rotation bearing is supported by Fluid Dynamic Bearing(FDB), this is not
keeping high speed spinning but also reducing resistance even eliminating and this make the
acceleration better.
The life of hard disk is up to the durability of this bearing supporting revolving axis.
Spindle motor rotate a disk media at regular speed.This device start to rotate as soon as
put power on and no matter what HDD read or write data,spindle motor always revolve.
Besides accurate reading from the media point of view is possible when maintain the constant
speed within 0.1%,rotation error. The control circuit of spindle motor receive the index data
from the spindle motor or media at every spin and check whether constant speed persists or not
then revise the speed. Spindle motor is applied to DC brushless motor.

⑫ Actuator

Hard disk has 2 disks so it has 4 written sides, and each side needs each written replay

device, 8 heads needed. This 4 heads can't work independently. Each head is connected with
one carriage and set as running altogether. For example, one head move at tenth track and
then the rest come to move at the same track. Retrieval(information searching) is a moving
the head to track properly. The faster searching speed, the better for a quick access.
It is profitable to use voice coil motor for a fast searching speed. Making narrow
the width and interval of track is for HDD capacity improvement so we can build more tracks
on written side so searching movements in head become subtle. Therefore servo control the
decision of HDD location. Magnetic disk is put standard signal for location marking from the
manufacturing step. Head read this to find the relative difference then run motor mediate
the head's location.

⑬ Magnetic Head

Magnetic field is formed around the conduct on passing electric current to conductor and
the direction and size of magnetic field are decided by those of an electric current.
Magnetic head build a minute gap in core (formed by ring) and pass an electric current then
strong magnetic leakage are occurred around gap thus magnetic particles of media vary the
direction according to the that of current: this is called recording. On the contrary, a
process induce magnetic signal to electric signal is called reading(decipherment).

⑭ Magnetic Disk

Recording carrier become a permanent magnet according to applying magnetic material to the
surface and change the magnetization direction of a electromagnet and it is possible to
store information during long term.

⑮ PCBA

PCBA is a circuit element concerning about HDD running and constructed in
engine IC,COMBO IC,read/write IC,ROM ,and sort of chip etc.

- Engine IC: contained RAM&Interface IC and exchange information to computer.

- COMBO IC: Controlling spindle motor & VCM running when HDD power on.

- Read/Write IC: read/write of HDD
