The CP3364 Summit is is a high performance 3.5
inch half-height drive with up to 360 Mbytes
(formatted) capacity, 12 ms average seek time and
6.7 ms average latency that is designed to operate
on an IBM PC/ATr or equivalent in translate mode.
The CP3364 offers high performance while maintaining
low power consumption to reduce power supply current
and system cooling requirements in disk arrays.
Typical applications are workstations, file servers,
multiuser systems and disk arrays.
Because the drive contains the Task File within
its control logic, it requires a simplified
adapter board to operate.

The timing is measured through the
interface with the drive operating at
nominal DC input voltages. The timing is
based upon the physical parameters of the
disk and may be affected by translation.
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

6.0 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
6.1 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
The dual microprocessor-controlled circuit card
provides the remaining electronic functions which
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.
6.2 Drive Mechanism
A brushless DC direct drive motor rotates the
spindle at 4498 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.
6.3 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.
6.4 Head Positioning Mechanism
The read/write heads are supported by a mechanism
coupled to a rotary voice coil actuator.
6.5 Read/Write Heads and Disks
Data is recorded on 95mm diameter disks through
miniaturized 3370 type thin film heads.
6.6 Customer Options
Up to two drives may be daisy chained together
utilizing the 40 pin Task File connector. The
maximum cable length is 18 inches. In order to
install more than one drive, it is necessary to
set a jumper option. The C/D jumper is used to
determine whether the drive is a master (drive C)
or slave (drive D). The drive is configured as a
master (drive C) when jumpered and as a slave
drive (D drive) when not jumpered. (Refer to
description of -PDIAG signal for further
information on master/slave in Conner drives.)
DSP & SS
This pair of jumpers determines the signals on pin
39 of the interface connector.
DSP SS Action
- spindle synchronization signal
X disabled on pin 39.
- activity LED signal available on
- spindle synchronization signal
X enabled on pin 39.
- activity LED signal disabled from
- pin 39 floating.
Master/slave in CAM compatible mode uses pin 39 in
a time multiplexed manner to indicate that a slave
drive is present. During power-on-reset or after
RESET is asserted, this line is asserted by the
slave drive within 400 ms to indicate its
presence. The master drive allows up to 450 msec
for the slave drive to assert -HOST SLV/ACT. -
HOST SLV/ACT is deasserted by the slave drive
following its acceptance of the first valid
command or after 31 seconds, whichever comes
Jumpers E1, E2, E3
E1 Jumper in disables spin-up at power-on.
The drive will automatically spin up when
it receives a command which accesses the
A drive select LED may be driven using two
alternative pins on this drive. Pin 39 can be
used to drive the LED if it is not configured for
Spindle Synchronization. The 16-pin auxiliary
connector (J3), pins 3 and 4 provide an open
collector drive signal and a current limiting
resistor connected to the other end of +5V.
The spindle synchronization signal is
alternatively available on pin 2 of J3.
7.0 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
The design features which allow greater shock
tolerance are the use of rugged heads and media, a
dedicated landing zone, closed loop servo
positioning and specially designed motor and
Ten base mounting points 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 integrator should
allow ventilation to the drive to ensure reliable
drive operation over the operating temperature
range. The drive may be mounted in any attitude.
The system integrator should also allow 0.060
inches (1.6mm) of free space and on each side of
the drive for head-disk-assembly (HDA) sway space
if the drive is expected to need operating shock
specifications. If the disk drive is mounted from
sides, the mounting provisions should clear the
baseplate of the HDA.
8.0 Measuring Drive Specifications
8.1 Seek Times
The timing is measured through the interface with
the drive operating at nominal DC input voltages.
The timing also assumes that the BIOS and PC
system hardware dependency have been subtracted
from timing requirements and that the drive is
operated using its' default translate parameters.
Average seek time is determined by averaging the
seek time for a minimum of 1000 seeks of random
length over the disk surface.
8.2 Start Time (Power Up)
Numbers specified assume that spin recovery is not
invoked. If spin recovery is invoked, the max
could be 40 seconds. Briefly removing power can
lead to spin recovery being invoked.
Drives are subjected to specified G level shock
for 11 milliseconds at 1/2 sine shock pulse. The
drive meets specification without suffering non-
recoverable READ or WRITE errors or other damage.
Drives are subjected to specified vibration levels
at 1/2 octave per minute sweep sine. The drive
meets the specification without non-recoverable
errors READ or WRITE errors or other damage.
9.0 Electrical Description
9.1 Power Connector
Power is supplied to the drive through a standard
4 pin DC power connector.
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
10.0 Host Interface
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.
10.2 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.
10.3 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.
10.4 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".
10.5 Pin Descriptions
Signal Name Dir Pin Description
-HOST RESET O 01 Reset signal from
the Host system which is
active low during power
up and inactive
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
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
RESERVED O 21,27,29
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 the drive and Host.
+HOST ALE O 28 Host Address Latch Enable. A signal used
to qualify the address lines. This signal
is presently not used by the drive.
GND O 30 Ground between the 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
-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 Passed diagnostic. 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 deactivates -PDIA 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 deactivates -PDIAG 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 A0,A1,A2 O 35
33,36 Bit binary coded address used to 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. NOTE: This signal
should be disabled by the Host when data
transfers are in progress.
-HOST CS1 O 38 Chip select decoded from the Host address
bus. Used to select three of the registers
in the Task File.
-HOST SLV/ACT I 39 Signal from the drive used either to drive
an active LED whenever the disk is being
accessed, as a signal for synchronizing
spindles of a drive array or as an
indication of a second drive present.
(See the Customer Options section
for further information).
GND O 40 Ground between the drive and host.
10.6 Auxiliary Connector
The Auxiliary connector is used to provide
optional signals at the front of the drive. No
