drive operating at nominal DC input voltage and nominal
operating temperature. The timing also assumes that:
- Bios and PC system hardware dependency have
been subtracted from timing measurements.
- The drive is operated using it's native drive
paramenters.
- The controller overhead, measured through the
interface, is the time it takes to start a seek
after the drive has been selected.
The average seek time is determined by averaging the seek
time for a minimum of 1000 seeks of random length over the
surface of the disk. These numbers assume spin recovery is
not invoked.If spin recovery is invoked, the maximum could
be 40 seconds. Briefly removing power can lead to spin
recovery being invoked.

Read/Write Mode occurs when data is being read from or
written to the disk.
Seek Mode occurs while the actuator is in motion.
Idle Mode occurs when the drive is not reading, writing
or seeking. The motor is up to speed and DRIVE READY
condition exists. Actuator is residing on last accessed track.
Standby Mode occurs when the motor is stopped and actuator
is parked. STANDBY MODE may occur after a programmable
time-out since last host occurs. The drive will leave
STANDBY MODE upon receipt of a command which requires disk
access or upon receipt of a spin up command.
Sleep Mode occurs when all electronics are disabled.

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. Its function is to
provide head selection, read pre-amplification, and write drive
circuitry.
The single 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
o Power Management
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 at
3833 RPM. 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
motor 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 rotary voice coil actuator.
5.5 Read/Write Heads and Disks
Data is recorded on 95mm diameter disks through 3370 type heads.
5.6 Error Correction
The drive uses a Reed-Solomon code to perform error detection
and correction. The software error correction polynomial is
capable of correcting one error burst with a maximum of 22 bits
or 2 error bursts of up to 11 bits each, per 512 byte block.
Single bursts of 11 bits or less are corrected on the fly (EOF)
with no performance degradation.
5.7 Master/Slave Configuration
The drive is designed to operate either as a Master Drive
(C Drive) or a Slave Drive (D Drive). This feature is
dependent on two drive settings; the status of hardware
Jumper M/S and the firmware setting of a feature bit.
When (M/S) is closed the drive will assume the role of a
Master Drive. When (M/S) is open the drive will act as
the Slave. In single drive configurations M/S must remain
in the closed position. The feature word bit 8 determines
if the drive will act according to ATA/CAM or ISA/Conner
protocol during master/slave detection.
When two drives are daisy chained on the interface,
commands are written in parallel to both drives, only the
selected drive will execute the command, except for the
diagnostic command. In that case, both drives execute the
command and the slave reports its status to the master via
the -HOST-PDIAG signal.
Drives are selected by the DRV bit in the drive/head
Register and by a jumper, on the drive designating it as
either a master or slave. When the DRV bit is reset,
the master drive is selected, and when the DRV bit is set,
the slave drive is selected. When drives are daisy chained,
one must be jumpered as the master and one as the slave.
When a single drive is attached to the interface, it must
be jumpered as the master. Throughout this document, drive
selection always refers to the state of the DRV bit, and
position of the master/slave jumper.
6.0 Electrical Description
6.1 Power Connectors
The drive has two power connectors; a standard 4 pin DC
power connector and a smaller 3 pin connector. Power must
only be supplied at one source.
The mating connector for the 4 pin connector is
AMP 1-480424-0 (Housing) and AMP 60619-4 (loose piece)
or 61117-4 (strip) contacts.
The following table describes the 4 pin power connector pins:
Pin Signal
2 GND
The mating connector for the three pin connector is
Molex series 54-84 Header, housing Molex part number
39-01-0033 and terminal part number 39-00-0031 (loose)
or 39-00-0023 (strip).
The following table describes the 3 pin power connector pins.

7.0 Host Interface
7.1 Description
The interface between the drive adapter and the drive is
called the Host Interface. The set of registers in the
I/O space of the Host controlled through the Host
Interface is known as the Task File. The physical
interface from the drive to the host is implemented using
a 40 pin connector. The pin descriptions follow.
7.2 Interface Connector
The recommended mating connector is Molex P/N 15-47-3401
or equivalent. Two drives may be daisy chained on this
connector, and the maximum cable length is 18 inches.
7.3 Signal Levels
All signal levels are TTL compatible. A logic "1" is
> 2.0 Volts. A logic "0" is from 0.00 Volts to .70 Volts.
The drive capability of each of the inbound signals is
described below.
7.4 Signal Conventions
All signals on the Host Interface shall have the prefix HOST.
All negatively active signals shall be further prefixed with
a "-" designation. All positive active signals shall be
prefixed with a '+' designation. Signals whose source are
the Host, are said to be "outbound" and those whose source is
the drive, are said to be "inbound".
These are the standard pin designators for the ISA/Conner
architecture.
Signal Name Dir Pin Description
-HOST RESET O 01 Reset signal from the Host system
which is active low during power
up and inactive thereafter.
GND O 2 Ground between drive and Host.
+HOST DATA I/O 3-18 16 bit bi-directional data bus 0-15
between the host and the drive. The
lower 8 bits, HD0- HD7, are used for
register & ECC access. All 16 bits
are used for data transfers. These
are tri-state lines with 24 mA drive
capability.
GND O 19 Ground between drive and Host.
KEY N/C 20 An unused pin clipped on the drive
and plugged on the cable. Used to
guarantee correct orientation of
the cable.
RESERVED O 21,27,28,29
GND O 22 Ground between drive and host.
-HOST IOW O 23 Write strobe, the rising edge of
which clocks data from the host data
bus, HD0 through HD15, into a register
or the data register of the drive.
GND O 24 Ground between drive and host.
-HOST READ IOR O 25 Read strobe, which when low enables
data from a register or the data
register of the drive onto the host
data bus, HD0 through HD15. The rising
edge of -HOST IOR latches data from
the drive at the host.
GND O 26 Ground between drive and Host.
GND O 30 Ground between drive and host.
+HOST IRQ14 I 31 Interrupt to the Host system, enabled
only when the drive is selected, and
the host activates the -IEN bit in
the Digital Output register.
When the -IEN bit is inactive, or the
drive is not selected, this output in
a high impedance state, regardless of
the state of the IRQ bit. The
interrupt is set when the IRQ bit is
set by the drive CPU. IRQ is reset to
zero by a Host read of the Status
register or a write to the command
register. This signal is a tri-state
line with 8 ma drive capacity.
-HOST IO16 I 32 Indication to the Host system that
the 16 bit data register has been
addressed and that the drive is
prepared to send or receive a 16 bit
data word. This line is tri-state
line with 24 mA drive capacity.
-HOST PDIAG I 34 ISA - At POR-PDIAG will be activated
by the slave within 1 ms. If the
master doesn't see -PDIAG active after
4 ms it will assume no slave is
present. -PDIAG will remain active
until the slave is ready to go not
busy or 14.0 seconds on a power on
reset. The master will wait 14.5
seconds or until the slave
de-activates -PDIAG on power on
reset before it goes not busy.
The slave will de-activate -PDIAG
and go not busy, if it is not ready
after the 14.0 seconds. Neither
drive will set ready or seek
complete until they have reached
full spin speed and are ready to
read/write.
During a software reset, -PDIAG
will be activated by the slave
within 1 ms. If the master doesn't
see -PDIAG active after 4 ms it
will assume no slave is present.
The slave will not de-activate
-PDIAG until it is ready to go not
busy or 400 ms. The master will
only wait 450 milliseconds or until
the slave de-activates -PDIAG before
it goes not busy. The slave will
only wait 450 milliseconds before it
activates -PDIAG and goes not busy.
The slave will not set ready or seek
complete until those states are
achieved.
After reset, -PDIAG will be used for
the diagnostic command in the
following manner. It is output by
the drive if it is the slave drive,
input to the drive if it is the
master drive. This low true signal
indicates to a master that the slave
has passed its internal diagnostic
command. This line is only inactive
high during execution of the
diagnostic command.
-HOST PDIAG I 34 CAM - DASP- (Drive Active/Drive 1
Present) This is a time-multiplexed
signal which indicates that a drive
is active, or that Drive 1 is present.
This signal shall be an open collector
output and each drive shall have a
10K ohm pull-up resistor.
During power on initialization or
after RESET- is negated, DASP- shall
be asserted by Drive 1 within 400 ms
to indicate that Drive 1 is present.
Drive 0 shall allow up to 450 ms for
Drive 1 to assert DASP-. If Drive 1
is not present, Drive 0 may assert
DASP- to drive an activity LED.
DASP- shall be negated following
acceptance of the first valid command
by Drive 1 or after 31 seconds,
whichever comes first.
Any time after negation of DASP-,
either drive may assert DASP- to
indicate that a drive is active.
+HOST A0,A1,A2 O 35-33- Bit binary coded address used to
36 select the individual registers in
the task file.
-HOST CS0 O 37 Chip select decoded from the host
address bus. Used to select some of
the Host accessible registers.
-HOST CS1 O 38 Chip select decoded from the Host
address bus. Used to select three
of the registers in the Task File.
-SPIN SYNC/ACT I 39 Signal from the drive used either to
drive an active LED whenever the disk
is being accessed or as an indication
of a second drive present. (See the
Customer Options section for further
information).
GND O 40 Ground between drive and host.
7.5 Auxiliary Connector
The Auxiliary connector is used to provide optional
signals at the front of the drive. No connection
should be made to the pins marked RESERVED.
These pins are reserved for factory test purposes
and improper connection may adversely affect the drive.
