1.3 GENERAL DESCRIPTION

The MK-150FASeries 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 ST506/412 size, mounting and power requirements

The MK-150FA Series supports the Enhanced Small Disk Interface (ESDI). ESDI provides device level

capabilities for multi-spindle

highly optimized applications.

The positioning system utilizes a rare earth magnet and a rotary voice coil actuatorto provide a 25 millisec-

ond 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 airrecirculatory system and a 0.3 micron lifetimefilter

to ensure a contamination-free environment and even thermal distribution.

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 levelS of read channel noise and enhances data recovery.

To further reduce read channel

nOise,

DC voltages are filtered before being used on the read channel.

Extensive use of VLSI minimizes the number of components and optimizes MTBF (Mean Time Between

Failures).
