3.0 GENERAL DESCRIPTION
3.1 Introduction
The Series .5000E streaming tape drive (Figure 1.0) is a family of
innovative, low cost, highly reliable }{.-inch wide cartridge tape
drives.
When utilized in the "streaming" mode at 90 ips, and using a standard
.!t.i,9-foot-long tape cartridge (Figure 1.1) the drive can record 20, or
( ~bytes of data, using the Ii- o;@track format, reseectiveJy•
./ Utilization of the 600-foot-long tape cartridge provides storage of
either 26.7 or 60 Mbytes of data with the 4 or 9 track format,
respectively.
The Series 5000E cartridge tape drive can be utilized for either
Winchester disk backup or general data storage in the streaming
start/stop or data distribution mode.
An optional intelligent formatter, available in either a half-high
module or external to the drive, will record either the QIC-24- or
Archive 8-inch QIC-11 data format using the QIC-02 defined
intelligent interface.
3.2 Physical Description
The drive consists of a die cast aluminum deck. The components
mounted on the deck are as follows:

Tape Hole Sensor Block Assembly
"Safe" and "Cartridge In" Switch Assembly
The Series 5000E is designed to have the same dimensional
parameters as a 5~-inch Winchester or Floppy Disk drive.
The control electronics are mounted on the deck. The components
are mounted on a 5.7 5-lnch-wide, 1.6-lnch-high, 8-inch-deep envelope
(Basic Interface), and 5.75-inch-wide, 3.25-inch-high, 8-inch-deep
envelope with the intelligent formatter included.
3.3 FWlctional Description
The Series 5000E can utilize either the 450-, or 600-foot tape
cartridge.
The type of cartridge being used is transparent to the user, due to the
drives automatic capability to select the proper write currents and
read gains for the respective cartridge being utilized.
The Series 5000E also utilizes the QIC-24 track reference burst to
automatically position the head to the center of the reference burst.
NOTE: This feature requires that the "Search" jumper be
removed.
The above feature minimizes misalignment of the head when reading
tapes generated by other drives utilizing the QIC-24 data format.
When the Series 5000E tape drive is in the WRITE mode, it will
automatically position the Read/Write head assembly to the
theorectical Track 0 position.
3.4 Drive Microprocessor
The microprocessor employed is the kernel for the device operation,
and maintains control of the stepping mechanism, drive motor, and
decodes all the commands from the formatter.
3• .5 Capstan Motor System
The capstan motor assembly is controlled by the drive
microprocessor. The speed is also monitored by the formatter, which
uses a signal derived from a tachometer. Instantaneous speed
variation is held within + 7 %, while long term speed variation is
limited to !. 3 %.
3.6 Head Carriage and Stepper Motor Assembly
Positioning of the head to the desired track is accomplished by a
stepper motor lead screw positioning mechanism. The drive signal to
the stepper motor is generated by the CPU on the formatter, and
interpreted by the drive microprocessor.
4

3.7 Read/Write Head Assembly
Reading and writing on the tape in either a 4-, or 9-track format is
performed by a two channel serpentine recording head, arranged with
"read, after write" poles with a full tape erase bar.
3.3 Tape Hole Sensor Assembly
The system for detection of End of Tape (EOT), Beginning of Tape
(BOT), Load Point (LP), and Early Warning (EW) holes utilizes optical
sensor assemblies, the output of which are synchronously clocked into
the formatter's CPU.
3.9 Daisy Chain Capability
The drive may be configured by the user to be constantly selected or
selected by any one of four available discrete select lines. The
selected (SLD) signal is sent to the formatter CPU and the acivity
LED.
3.10 Activity LED Indicator
The acitvity LED is illuminated when the drive is selected and busy.
It is enabled by the select lines in conjunction with the user
selectable DIP shunts.

5.4 Cartridge Loading and Unloading
The cartridge can be loaded into the Series 5000E drive in one
orientation only. This is accomplished by pushing the cartridge into
the open slot until further travel is restricted and released. The
cartridge can be unloaded, even during operation, by simply re pea ting
the load procedure until the cartridge is released and free. (Figures
2.0, 2.1)
5.5 Mean Time between Failure (MTBF)
The design goal of the Series 5000E is for MTBF of greater than 8.000
P.O.H., inclusive of power on and operation time, but excluding any
maintenance periods. It is assumed for this calculation that the drive
will run at a 20% duty cycle.
5.6 Mean Time to Repair (MTTR)
The MTTR of the Series 5000E is 0.5 Hours.
5.7 Preventative Maintenance
NOTE: ALWAYS TURN POWER OFF.
After the insertion of a new tape cartridge, the recording head and
tape cleaner should be cleaned after approximatley two hours of use,
and every 8 hours thereafter of actual use.
The recommended cleaning procedure is to use a lintless cotton swab
soaked with Freon TF or IBM tape cleaner only.
NOTE: Isopropyl Alcohol will leave a residue on the head assembly,
and should not be used whenever possible.

7 .O OPERATION
7.1 Unpacking the Drive
The drive is packaged in a protective container to minimize the
possibility of damage during shipment. The following is the
recommended procedure for unpacking the drive:
1. Place the shipping container on a flat surface.
2. Open the container and inspect the internal damage (if any}.
3. Remove the drive from the container.
4. Check the contents of the container against the packaging slip.
10

.5. Visually inspect the contents of the package for any physical
damage.
6. Notify the carrier immediately if there is any damage.
7 .2 Pre-Installation Checklist
Prior to applying power to the drive, the following procedure should
be implemented:
1. Check to ensure that there are no loose components on the
drive.
2. Check to ensure that when the tape cartridge is inserted, the
head assembly loads properly.
3. Check the security of the front panel.
ii-. Check to see if the drive belt is in place.
5. Check the security of the printed circuit boards.
6. Check the security of all connectors, and ensure they are
properly orientated, i.e. pin 1 to pin 1.
7 .3 Mounting the Drive
The drive has been designed to be mounted either horizontally or
vertically. If mounted vertically it ls recommended that the
cartridge door is physically located above the activity LED.
Four 6/32 tapped mounting holes are provided on the bottom of the
drive. When installed in either plane, horizontal or vertical, only
three mounting screws are required to securely fasten the drive in
place.
Any mounting scheme in which the drive is part of the structural
integrity of the enclosure is not permitted.
Mounting schemes should allow for adjustable brackets or the
incorporation of resilient members to accommodate tolerances.
In addition, it is recommended that mounting schemes include no
more than two mounting surfaces.
The drive is manufactured and tested with some internal alignments,
which must be maintained. Therefore, it ls important that mounting
hardware does not introduce significant stress on the drive chassis.
7.3.1 Dust Cover
The design of an enclosure should incorporate a means of
prevention from contamination, i.e. dust, lint, and other
dust producing material, as the drive does not have a dust
cover.
11

7 .3.2 Cooling
,Heat dissipation from a single drive is normally 16 watts,
54 BTU/hour (Basic Drive), under high load conditions.
When the drive ls mounted to allow free flow of air over
the components, normal convection cooling will be
sufficient to operate within the specified temperature
range. .
When the drive is mounted in a confined enclosure, air
flow must be provided to maintain the specified
temperature range.
When forced alr is introduced, the flow must be directed
outward from the drive through a filter to avoid the
introduction of contaminants. Do not intake air through
the drive, as it will cause contamination in critical areas.
7 .4 Tape Cartridge
The tape cartridge used is a standard ~-inch tape (Figure 1.1).
The following are recommended 3M tape cartridges to be utilized
with the Series 5000E tape drive:
DC 600A
DC 300XL/P
DC 300XL
600ft Data Cartridge
4.50ft Data Cartridge
450ft Data Cartridge
7.4.1 Cartridge Loading
The tape cartridge is loaded into the drive by pushing it
into the front loading slot. The tape should be loaded
towards the LED indicator side of the drive. The tape is
loaded by pushing forward until the cartridge is latched.
The head/carriage assembly is loaded, and the tape is
ready for operation. (Figure 2.0)
7 .4.2 Cartridge Unloading
The tape cartridge is unloaded by simply pushing it into
the drive until it stops, thus releasing the cartridge and
unloading the head/carriage assembly, allowing it to be
ejected from the drive. (Figure 2.1)
7.4.3 Write Protect Feature
The data on the tape cartridge may be protected from
being overwritten by turning the Write Protect indicator
1800 to the SAFE posl ti on.
7 .4.4 Handling and Storage
The tape cartridge must not be exposed to dirt, moisture,
or extreme tempearture.
12

The user should never open the tape access cover to
expose the tape when the cartridge is not in use, and
should never physically touch the tape. The oils and acids
of the hand can contaminate the tape surface, and
magnetic coating.
A properly handled tape cartidge will provide long,
reliable service. Broken, chipped, or cracked cartridges
should be discarded immediatley.
NOTE:
ANY ATTEMPT TO UTILIZE A
DAMAGED CARTRIDGE MAY RESULT
IN DAMAGE TO THE TAPE DRIVE!
Storage of tape cartridges should be in accordance with
the manufactureres recommendations. Never place
cartridges near a device which may generate a strong
magnetic field.
8.0 INTERFACE DESCRIPTION (Basic Drive)
8.1 Interface Characteristics
There are 25 signal lines at the Basic Tape Drive Interface. Fifteen
(17) lines are used for signals that are generated by the formatter
CPU, and seven (7) lines are used for signals that are generated on
the Basic Drive. One (1) line is reserved for future use.
The signals are transmitted via a conductor flat ribbon cable which
must not exceed 3 meters in length.
3.2 Signal Levels
All voltage measurements are at the drive connector with the
terminators installed.
Standard TTL are used on signal lines to the formatter as follows:
FALSE, logic 0 (Hlgh) =2.4 to 5.25 VDC
TRUE, logic l (Low) =0.0 to 0.55 VDC
Standard TTL levels are required on signal lines to the drive as
follows:
FALSE, logic o(High) =2.0 to .5.2.5 voe
TRUE, logic l (Low) = O.O to 0.80 VDC
8.3 Signal Termination
The recommended termination is 220 ohms to +.5 voe, and 330 ohms
to ground. The resistor network tolerance shall be .::.10%. In a
standard daisy chain configuration, all lines to the formatter shall be
13

terminated at the formatter, while the signals at the last drive in the
chain will also be terminated. (Figure 3.0) In the event that the
formatter is in the middle of the daisy chain, all signal lines shall be
terminated at the extreme ends of the bus. (Figure .3.1)
8.4 Signal Loading
Signals transmitted from the drive are capable of driving two
termination networks and a single TTL load. Signals received by the
drive are loaded by only one TTL load at each drive plus the
necessary termination network. It ls recommended that the
formatter not load the signal lines from the drive by more than one
termlna tion network and one TTL load. (Figure 3.2)
8• .5 Interface Connector
The interface connector on the Series 5000E is a 50-conductor flat
ribbon cable. The recommended mating connector is a 3M PN 3425
or equivalent.
