5.0 Functional Description
The drive contains all necessary mechanical and
electronic parts to interpret control signals,
position the recording heads over the desired track,
read and write data, and provide a contaminant free
environment for the heads and disks.
5.1 Read / write and Control Electronics
One integrated circuit is mounted within the sealed enclosure
in close proximity to the read/write heads. It's function
is to provide head selection, read amplification
and write drive circuitry.
The Microprocessor-controlled circuit card provides the
remaining electronic functions which include:
o Read/Write Circuitry
o Rotary Actuator Control
o Interface Control
o Spin Speed Control
o Dynamic Braking
At power down the heads are automatically retracted to the
inner diameter of the disk and are latched and parked on a
landing zone that is inside the data tracks.
5.2 Drive Mechanism
A brushless DC direct drive motor rotates the spindle. The
motor.spindle assembly is dynamically balanced to provide
minimal mechanical runout to the disks. A dynamic brake
is used to provide a fast stop to the spindle motot and
return the heads to the landing zone when power is removed.
5.3 Air Filtration System
The head-disk assembly is a sealed enclosure with an
integral 0.3 micron filter which maintains a clean
environment for the heads and disks.
5.4 Head Positioning Mechanism
The read/write heads are supported by a mechanism coupled
to a rotory voice coil actuator.
5.5 Read/Write Heads and Disks
Data is recorded on 95mm diameter disks through 3370 type
thin film heads.
5.6 Erorr Correction
The error detection and correction code (EDAC) implementation
in this generation of Conner disk drives is a Reed Solomon
code with single burst on-the-fly correction. The code will
correct any single burst of up to 11 bits in length on the
fly. The code will correct two error bursts of up to 11 bits
win length in firmware and detect three error bursts of up
to 11 bits in length. The single burst detection capability
of the code is 51 bits.
5.7 Customer Options
5.7.1 SCSI Bus Address
There are three jumpers available for configuration of
SCSI ID: E1, E2, and E3.
Jumper Options
E1 = 1
E2 = 2
E3 = 4
Delay Spin
A jumper in the E4 location, disables spin up on power-on.
Disabling spin up on application of power can also be enabled
by setting the DSPN bit in MODE SELECT page 0.
E4 DSPN Result
In 0 Spin Disabled
In 1 Spin Disabled
Out 0 Spin up on Power On
Out 1 Spin Disabled
5.7.2 SCSI Parity
SCSI parity is always enabled in both directions.
5.7.3 SCSI Termination
Three removable resistor packs located behind the 50-pin
SCSI interface connector provide SCSI bus termination.
Terminator power (TERMPWR) output on pin 26 can be disabled
by removing the jumper in loc. E5, which is located behind
the 50 pin SCSI interface connector.
6.0 Power Connector
The drive has a 4-pin DC power connector mounted on the PCB.
The recommended mating connector is AMP part number 1-480424-0
utilizing AMP pins, part number 350078-4 or equivalent.
7.0 Recommended Mounting Configuration
The drive is designed to be used in applications where the unit
may experience shock and vibrations at greater levels than larger
and heavier disk drives will tolerate.The design features which
allow greater shock tolerance are the use of rugged heads and
media, dedicated landing zone, closed loop servo positioning and
specially designed motor and actuator assemblies.
Ten base mounting pionts are provided to the customer. The
drive is mounted using 6-32 x 1/8" max. insertion for the
sides, and 1/4" insertion for the bottom. The system intrgrator
should allow ventilation to the drive to ensure reliable drive
operation over the operating temperature range. The drive may be
mounted in any attitude.
