2. GENERAL DESCRIPTION

MK3006GAL/MK4006GAH/MK6006GAH
The
MK3006GAL/MK4006GAH/MK6006GAH
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
loop servo control system which have made high recording density of 149.6 M bit/mm
2
bit/in )(MK3006GAL/MK6006GAH), 131.7 M bit/mm
of 15 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.
MK3006GAL/MK4006GAH/MK6006GAH
The
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.
The drive provides a carriage lock mechanism which is activated automatically upon power down in order to
prevent head/media from being damaged when it is not operating or under shipment.
The printed circuit board which is set externally to the HDA and equipped with all the electric circuitry
necessary to operate the drive except the head drivers . The power supply and interface signal connectors
are mounted on the board. Only the head control IC's are located within the HDA. The circuitry perform the
following functions:
Read/Write, Task File Control, Spindle Motor Control, Seek and Head Positioning Servo Control, Abnormal
Condition Detection and Shock Sensor Control.
