The CP2044PK drives are 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 E1 and the firm-
ware setting of a feature bit. When (E1) is closed, and the feature
bit is set, the drive will assume the role of a Master Drive.
When E1 is open, and the feature reset, the drive will act as the
Slave. In single drive configurations E1 must remain in the closed
position.

The drive may be mounted in any attitude!
Recommended Mounting Configuration
----------------------------------
This CP2044PK is designed to be used in applications where the unit
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.
Four (4) side mounting points and four (4) bottom mounting points are
provided to the customer. The drive is mounted using 3mm x 0.5mm
thread screw. The screw insertion depth should not exceed 4mm into
the mounting holes. 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.
Interface Connector
-------------------
The CP2044PK drive has a 44 pin right angle interface/power connec-
tor mounted on the PCB. The recommended mating connector is DuPont
part number 69764-044 or equivalent. The maximum cable lenght is two
feet.
Magnetic Field
--------------
The externally induced magnetic flux density may not exceed 6 gauss
(DC - 700KHz) or 1.0 gauss (700KHz - 1.5MHz) as measured at the
drive surface.
Acoustic Sound Emission
-----------------------
Pressure: 34 dB(A) max at 1 meter.

Key Features
------------
The CP2044PK is a family of high performance 2.5 inch low-profile
disk drives with formatted capacities of 42.6 megabytes.
The CP2044PK drive has a 19 ms average seek time and is designed to
operate on IBM PC/AT or equivalent computers.
The drive feature a low power requirement and high shock resistance,
enabling battery operation in a portable environment.

- Master/Slave
Universal Translate Mode
------------------------
Conner has established a Universal Translate Mode which enables the
user to configure the drive in an AT environment to any cylinder,
head, and sector configuration desired. The translate configuration
is limited only by the maximum capacity of the drive. Upon initial
power up to the drive it will default to a predetermined configura-
tion shown below:
Cylinders Heads Sectors
CP-2044PK 980 5 17
After the drive is ready, the host system may issue INIT DRIVE PARMS
COMMAND (command code 91H) to alter the translate configuration
(number of heads and number of sectors per track). The drive para-
meters will then be saved in EEPROM for subsequent drive operations.
Seek Times
----------
+----------------------------------+--------+
|Physical track to track max. | 5 ms |
|Logical max. | 10 ms |
+----------------------------------+--------+
| Average msec. typ. | 19 |
| Average msec. max. | 40 |
+----------------------------------+--------+
|Latency msec. avg. | 8.7 |
+----------------------------------+--------+
The timing is measured through the interface with the drive
operating at nominal DC input voltages. The timing also assumes
that:
- BIOS and PC system hardware dependency have been
subtracted from timing measurements.
- The drive is operated using its translation parameters.
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.
Write Precomp Register
----------------------
(CSO, address 1 write only) A register previously used to set write
precompensation, now is used only for enabling or disabling LOOK
AHEAD READs or to activate extended commands.
Functional Description
----------------------
The CP2044PK 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
head selection, read preamplification, and write drive circuitry.
The single microprocessor controlled circuit card provides the
remaining electronic functions which include:
- Read/Write Circuitry
- Rotary Actuator Control
- Interface Control
- Spin Speed Control
- Dynamic Braking
- Power Management
At power down or the start of STANDBY MODE or SLEEP MODE 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 3486 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, or upon initiation of STANDBY MODE.
Air Filtration System
---------------------
Within the sealed enclosure, a 0.3 micron filter which provides a
clean environment for the heads and disks.
Head Positioning Mechanism
--------------------------
The read/write heads for the CP2044PK are supported by a mechanism
coupled to the voice coil actuator.
Read/Write Heads and Disks
--------------------------
Data is recorded on 65mm diameter thin film disk through micro-
miniature thin film heads.
Error Correction
----------------
The CP2044PK use a Reed-Solomon code to perform error detection and
correction. The error correction polynominal 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 with no performance degradation.
Reliability and Maintenance
---------------------------
MTBF 100,000 hours POH (population is min. of 100
units)
MTTR 10 minutes typical
Preventive Maintenance None
Component Design Life 5 years
