The drive may be mounted in any attitude!
Recommended Mounting Configuration
----------------------------------
The CP3040 is designed to be used in applications where the units may
experience shock and vibrations at greater levels than larger and
heavier disk drives.
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 actuator
assemblies.
Ten base mounting points are provided to the customer. The drive is
mounted using 6-32 screws;1/8" max. insertion for the sides, and 1/4"
max. insertion for the bottom. The system integrator should allow
ventilation to the drive to ensure reliable drive operation over the
operating temperature range.
For additional vibration isolation, an external suspension system
may be used.
Cable Requirements
------------------
A 50-conductor flat cable or 25-conductor twisted pair cable is re-
quired. The maximum cable length is 6.0 meters (19.68 ft).
The cable characteristic impedance should be 132 ohms 10% with a
minimum conductor size of 28 AWG.
Connector Requirements
----------------------
The drive connector is a 50-conductor connector which consists of two
rows of 25 male pins on 100 mil centers.
The cable connector is a 50-conductor non-shielded connector which
consists of two rows of 25 female contacts on 100 mil centers.
Power Connector
---------------
The drive has a 4-pin DC power connector (J3) mounted on the PCB. The
recommended mating connector is AMP part number 1-480424-0 utilizing
AMP pins (part number 350078-4 or equivalent).
Electrical Description ---------------------- The CP3040 uses open collector drivers. All assigned aignals are terminated with 220 ohms to +5 volts and 330 ohms to ground. The termination resistors are removable for multi-device configurations.
Cabling
-------
Connect the power cable to J3. Connect the SCSI interface cable to
J2. Bus termination is required on the last device of the SCSI bus.
Diagnostic Routines
-------------------
The microprocessor performs diagnostics upon application of power.
If an error is detected, the drive will not become ready.
SCSI Termination
----------------
There are three removable terminators; RP1, RP2 and RP3. They can be
removed from the drive if bus termination is provided elsewhere in
the system.
Terminator Power
----------------
Terminator Power (TERMPWR) is supplied through a diode to prevent the
back-flow of power to the drive. TERMPWR has the following characte-
ristics:
Supply voltage 4.0 VDC to 5.25 VDC
Minimum Source Drive Capability 800 ma
Maximum Sink Capability 1.0 ma sink capability
with a 1.0 amp fuse
Magnetic Field
--------------
The disk drive will meet its specified performance while operating in
the presense of an externally produced magnetic field under the
following conditions:
+------------------+------------------+
|Frequency | Field Intensity|
+------------------+------------------+
| 0 to 700 Khz | 6 gauss maximum|
| 700Khz to 1.5Mhz | 1 gauss maximum|
+------------------+------------------+
Acoustic Noise
--------------
The sound pressure level will not exceed 40 dBA at a distance of 1
meter from the drive.
Features
CONNER CP3040 PRODUCT MANUAL 00501-016
Key Features
------------
The Conner Peripherals CP3040 is a 3.5 inch low-profile (1.00") disk
drive which offers high performance with low power consumption.
Using the Small Computer System Interface (SCSI), which is
compatible with the Common Command Set (CCS), the disk drive
provides 40 Mbytes of formatted storage.
Key features include:
- Low power requirements enabling battery operation in portable environments
- High performance rotary voice coil actuator with embedded servo system
- Two of seven run length limited code
- High shock resistance
- Internal air filtration system
- Sealed HDA
- Automatic actuator latch against inner stop upon power-down
- Microprocessor-controlled diagnostics routines that are auto- matically executed at start-up
- Automatic error correction and retries
- Block size: 512 bytes
- 8Kbyte data buffer with look-ahead caching
- 1:1 Interleave
Seek Times
----------
+----------------------------------+--------+
|Track-to-Track msec. | 8 |
+----------------------------------+--------+
| Average msec. typ. | 25 |
| Average msec. max. | 50 |
+----------------------------------+--------+
|Latency msec. avg. | 8.4 |
+----------------------------------+--------+
The timing is measured through the interface with the drive
operating at nominal DC input voltages. The timing also
assumes that the I/O driver overhead and system hardware de-
pendency have been subtracted from timing measurements.
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.
Output Characteristics
----------------------
Each signal driven by the drive has the following output character-
istics when measured at the drive connector:
+--------------------------------+----------------------------+ |Signal Assertion | 0.0 VDC to 0.4 VDC | +--------------------------------+----------------------------+ |Minimum Driver Output Capability| 48ma (sinking) at 0.5 VDC | +--------------------------------+----------------------------+ |Signal Negation | 2.5 VDC to 5.25 VDC | +--------------------------------+----------------------------+
Input Characteristics
---------------------
Each signal received by the drive must have the following input
characteristics when measured at the drive connector:
+--------------------------------+----------------------------+ |Signal Assertion | 0.0 VDC to 0.8 VDC | +--------------------------------+----------------------------+ |Minimum Total Input Load | -0.4ma at 0.4 VDC | +--------------------------------+----------------------------+ |Signal False | 2.0 VDC to 5.25 VDC | +--------------------------------+----------------------------+
Functional Description
----------------------
The CP3040 disk 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.
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
one of two head selection, read preamplification, and write data
circuitry.
The single microporcessor-controlled circuit card provides the re-
maining electronic functions, which include:
- Read/Write Circuitry
- Rotary Actuator Control
- Interface Control
- Spin Speed Control
- 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.
Drive Mechanism
---------------
A brushless DC direct drive motor rotates the spindle at 3557 RPM.
The motor/spindle assembly is balanced to provide minimal mechanical
runout to the disks and to reduce vibration of the HDA. A dynamic
brake is used to provide a fast stop to the spindle motor when power
is removed.
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.
Head Positioning Mechanism
--------------------------
The two read/write heads are supported by a mechanism coupled to a
voice coil actuator.
Read/Write Heads and Disks
--------------------------
Data is recorded on 95mm diameter disk through 3370 type thin film or
composite metal in gap heads.
Error Correction
----------------
The CP3040 disk drive performs internal error correction. The six-
byte error correction polynominal is capable of correcting one error
bursts with a maximum of 8 bits per 512-byte block.
Reliability and Maintenance
---------------------------
MTBF 50,000 hours (POH); population is minimum of
100 units
MTTR 10 minutes typical
Preventive Maintenance None
Component Design Life 5 years
Safety Standard
---------------
The CP3040 disk drive is designed to comply with relevant product
safety standards such as:
- UL 478, 5th edition, Standard for Safety of Information Processing and Business Equipment, and UL 1950, Standard for Safety of Information Technology Equipment.
- CSA 22.2#154, Data Processing Equipment and CSA 22.2#220, Inform- ation Processing and Business Equipment.
