VANGO(VL40)
SAMSUNG HARD DISK DRIVE
Enhanced
IDE
The existing IDE specification enable to adhere only 2 drives and transferring speed was low.
But HDD efficiency are resulted to low the whole capacity according to getting system efficiency
higher. Enhanced IDE has specification of revised IDE-AT interface by current BIOS and
528Mb
barrier and we settled the low speed problem with this new spec. Same as Fast-IDE Interface
or Local Bus IDE-AT Interface.
EOL
End of Life.
EPROM
Erasable programmable read only memory.
EVT
Engineering verification test.
FAT
File allocation table.
Data table is recorded at the most outer side of disk, inform sector
location and order of each recorded file to Operating system.
FCI
Flux change per inch. magnetization rotation density per unit inch.
FCI/FCPI/Flu
x Density
Flux Change Per Inch. Magnetization rotating density per unit inch. Concerned with BPI, this
value is decided by track has maximum radius. BPI is proportion to FCI according to difference
of coding method.
FDD
Floppy Disk Drive.
5.25"/3.5" drive is used for PC
FILTER
Components filtering particle from the flowed air to the inside/outside of HDA.
Firmware
Hardware control program, this is stored in
Flash
Memory
Among PROM of the memory for searching only which can re-write, memory chip enable to
rewrite and erase the old contents electrically.
Flexure
Assembly
Control rising by Slider ABS, flying height of slider and make slider move to proper track by
connecting to head positioning mechanism.
Flux Density
Flux density, the number of magnetic field pattern can be recorded on the disk surface.
Flying
Height
Distance between Read/write head and disk surface. Air resistance due to disk rotation can
maintain this distance, the small flying height is, the large data recording density is, but it need
more specified mechanical design.
Form factor
Industrial specification decided diameter of Disk.
3.5", 2.5" in case of Samsung.
Format
Recording the particular signal to divide track and sector and this information should be recorded
on disk in first before user want to store data. Be careful because formatting erase all recorded
information.
Formatted
capacity
Available HDD capacity after HDD formatting.
FPC
Flexible Printed Circuit, or PCC, inputted parts enable to flow current to the flexible material.
(Polemize)
FPC ASS'Y
Status of soldering IC, CAPACITOR, 14PIN CONNECTOR to FPC surface or connecting
HOLDER-FPC, SUPPORT-FPC, CLIP-FPC.
GASKET
Parts made of rubber to protect inner inflow air and moist from the outside of HDD
GigaByte(G
B)
Data storing unit. Accurately 1,073,741,824 bytes(1024*1024*1024), i.e. 1,000MB
GMR Head
Giant Magneto Resistive head. New type head of MR head.
Half height
One of the standard height specification of HDD and the real height is 1.6inch
Hard
Error/Soft
Error
Hard error is a continuous misreading due to defect of disk surface) and it can read correct
data if in case of read again, we call this soft error.
HDA
Head Disk Assembly, half assembled product of HDD. SPINDLE MOTOR, DISK, HSA, VCM etc.
are sealed within Base and Cover.
HDA label
Label remarked assembly status of Disk/Head by 5digit-english & number.
