1.3 GENERAL DESCRIPTION
The MK-150FA Series is a family of 5.25-inch Winchester disk drives designed primarily to be incorporated
into systems supporting multi-user and multi-tasking applications. Three models comprise the MK-150FA
Series: MK-153FA (86.5 MB), MK-154FA
(121
MB) and MK-156FA (173 MB).
All drives comply with the
The MK-150FA
Series supports the Enhanced Small Disk Interface (ESDI). ESDI provides device level
capabilities for multi-spindle
ST506/412 size, mounting and power requirements
or
highly optimized applications.
The positioning system utilizes a rare earth magnet and a rotary voice coil actuator to provide a 25 millisecond average
seek
time and a 45 millisecond
maxim~m
seek time.
The Head Disk Assembly (HDA) is enclosed in a die cast aluminum base plate and shroud and incorporates
numerous safety features to maximize reliability:
The base plate and shroud assembly provides mechnical mounting and EMI (Electronic
Magnetic Interference) shielding for the heads, disks and actuator.
The sealed assembly incorporates an air recirculatory system and a
0.3 micron lifetime filter
to ensure a contamination-free environment and even thermal distribution.
in
A barometric filter
the HDA provides ambient pressure equalization.
When power is removed, a fail-safe system automatically returns the heads to a dedicated
landing zone and a solenoid automatically locks the carriage in this location. This prevents
head
and media damage during transit.
Use of a center stack servo system improves head positioning accuracy across the full environmental
operating range and allows servo writing to be performed with the disk stack mounted in the drive.
Careful planning in regard to the location of components on the circuit card, especially those with electrical
noise potential, contributes to very low
