3. GENERAL DESCRIPTION
The
MK1032GAX
which is noted hereinafter as
MK1032GAX
or as
the drive
comprises a
series of intelligent disk drives .
The drive features an ATA-2 / 3 / 4 / 5 / 6 interface embedded controller that requires a simplified adapter
board for interfacing to an AT or AT compatible bus. The drives employ Winchester technology and a closed
board for interfacing to an AT or AT compatible bus. The drives employ Winchester technology and a closed
loop servo control system which have made high recording density of 129.0 M bit/mm
2
(83.2G
bit/in
2
)(

) and average access time of 12 msec with highest reliability of 300,000 hours for
MTTF (Mean Time to Failure) possible.
The drive is distinctive for its small and light body with 9.5mm height and 102 grams of weight.
The
MK1032GAX
consists of an HDA (Head Disk Assembly) and a printed circuit board. The HDA has a
sealed module which contains a disk spindle assembly, a head actuator assembly and an air filtration
system. This HDA adopts Winchester technology which enhances high reliability. The actuator is a rotary
voice coil motor which enables high-speed access.

The disk is driven directly by a DC spindle motor. Air filtration is provided by a high performance air filtration
system using both breather and circulation filters.
