TLZ06 Cassette Tape Drive Product
Description
1.1 Overview
The TLZ06 cassette tape drive provides you with high capacity, off-line data
storage. Depending on the 4 mm data cassette tape used, the unit can typically
store:
Tape Type (see NOTE 1.)

No Compression

Compression

TLZ04-CA (60 m)

1.3 GB

2.6 GB

TLZ06-CA (90 m)

2.0 GB

4.0 GB (see NOTE 2.)

NOTE
1. The TLZ06 is compatible with TLZ04 (60 m) cassette tapes in the
noncompressed mode only.
2. The 4.0 GB measurement is typical for a 2-to-1 data compression
ratio, but the actual ratio is dependent on the data.

The maximum time to backup (read or write) on a TLZ06 cassette tape in a
continual (streaming) mode is system dependent. The efficient use of streaming
mode is determined by your operating system. Please refer to your system
software documentation.

TLZ06 Cassette Tape Drive Product Description 1–1

1.1.1 System Support
As of this printing, the TLZ06 drive is supported by VAXstation systems and
DECstation systems. Your particular system must have a standard SCSI
(small computer system interconnect) port, or a KZQSA (Q–bus to SCSI
adapter).
VAXstation systems can use the VMS or ULTRIX operating systems.
DECstation systems use the ULTRIX operating system. Consult with your
Digital sales support person for operating systems supporting this device.

1.2 Design Features
The TLZ06 cassette tape drive uses state of the art technology. The TLZ06
cassette tape drive’s design incorporates both digital data storage (DDS) and
digital audio tape (DAT) recording technologies.

1.2.1 What is Digital Audio Tape (DAT)?
Digital audio tape (DAT), such as TLZ06 cassettes, takes advantage of the
TLZ06 tape drive’s helical scan technology. This technology allows data to
be stored diagonally on tape. As such, DAT allows more data to be stored on
tape. Also, DAT recording minimizes ‘‘crosstalk,’’ providing you with more data
integrity.

1.2.2 What is Digital Data Storage (DDS)?
Digital data storage (DDS) uses a recording format that supports the use of
digital audio tape for computer applications. The DDS/DAT format allows
you to back up 2 gigabytes of data in approximately 3 hours minimum with
no operator intervention. In addition, this format has three levels of error
correction, which ensures high data integrity.
NOTE
Use of Non-DDS media may result in degraded drive performance and
is not recommended by Digital Equipment Corporation.

Installing the Tabletop Drives
2.1 General
This chapter shows you how to install the TLZ06-DA tabletop cassette tape
drive or TLZ6L-DA tabletop auto loader on systems with an external SCSI
connector. Read the following sections to complete the installation.

2.2 Shut Down, Halt, and Power Off the System
If you are installing a TLZ06-DA tabletop cassette tape drive or TLZ6L-DA
tabletop auto loader on a running system, have your system manager perform
the following steps:
1. Shut down the operating system.
2. Halt the system.
3. Set all system power switches off.

Installing the Tabletop Drives 2–1

2.3 Selecting the SCSI Address
To familiarize yourself with the TLZ06 drive:
1. Refer to Figure 1–1 for the location of the buttons, switches, and connectors
on the tabletop drives.
2. Note that all connections are made at the rear of the drive.
Your system uses a SCSI ID switch (Figure 1–1) to identify, or address, the
drive. The SCSI ID is factory set at 5. If you are installing the drive on a
system that is already using SCSI ID 5, use any available SCSI ID. (You may
have to consult your system manager.)
To set/change the SCSI address:
1. Locate the SCSI address switch at the rear of the drive.
2. Select the SCSI address for the drive:
•

TLZ06-DA — Press the + or - button until the desired address (0
through 7) appears in the window.

•

TLZ6L-DA — Set the switches according to Table 3–1.
NOTE

If you are installing any other drive variant, refer to Chapter 3.
Turn off all power before connecting the cables and the terminator.
The drive must be turned off and then on for switch settings to take
effect, or a SCSI bus reset must be received.

2–2 Installing the Tabletop Drives

The tabletop drives provide two SCSI connectors to allow daisy chaining.
Either connector can connect to the host computer or any SCSI device in a
daisy chain.
•

If the tabletop is the last drive in the chain, a single interface cable is
attached to one connector and a SCSI terminator (PN 12-30552-01) is
installed in the other connector.

•

If the drive is within the chain, the interface cable from the preceding
device is connected in one connector; an interface cable is also connected
from the other connector to the following device.
NOTE
Make sure that the last SCSI device on the bus is terminated correctly.

2.4 Connecting a SCSI Signal Cable — Drive to System
If you are connecting a TLZ06-DA drive or TLZ6L-DA auto loader
directly to your system, you should use the SCSI signal cable supplied
as part of your system installation kit.
If you do not have this cable, contact your Digital sales representative. You
should use a cable supplied by Digital Equipment Corporation. Failure to do
so can result in degraded performance of your tabletop drive.
To connect a SCSI cable — drive to system — perform the following:
1. Connect one end of the cable to the system SCSI connector.
2. Connect the other end of the SCSI signal cable to either SCSI connector on
the rear of the TLZ06-DA drive or TLZ6L-DA auto loader.
3. Secure the SCSI cable by snapping the wire cable clamps (on either side of
the SCSI connector) into place.
4. Connect the SCSI terminator to the other SCSI connector on the rear of
the TLZ06-DA drive or TLZ6L-DA auto loader.
5. Secure the terminator by snapping the wire cable clamps (on either side of
the SCSI connector) into place.

Installing the Tabletop Drives 2–3

2.5 Adding Another Tabletop Drive — Drive to Drive
If you have one SCSI device already connected to your system, you can connect
the TLZ06-DA drive or TLZ6L-DA auto loader to that device. For drive to
drive connections, use the 50-pin to 50-pin SCSI signal cable (PN 17-01351-01)
supplied with the tabletop drive.
1. If present, remove the SCSI terminator from the existing SCSI drive.
2. Connect one end of the SCSI signal cable (PN 17-01351-01) to the existing
SCSI drive, observing the correct orientation of the cable connector.
3. Secure the SCSI cable by snapping the wire cable clamps (on either side of
the SCSI connector) into place.
4. Connect the other end of the SCSI signal cable to either SCSI connector
on the TLZ06-DA drive or TLZ6L-DA auto loader, observing the correct
orientation of the cable connector.
5. Secure the SCSI cable by snapping the wire cable clamps (on either side of
the SCSI connector) into place.
6. Connect the SCSI terminator to the other SCSI connector on the TLZ06-DA
drive or TLZ6L-DA auto loader, observing the correct orientation of the
cable connector.

2.6 Connecting the Power Cable
The tabletop drives have an autoranging power supply. Refer to Table A–1 for
voltage specifications.
To connect the power cable, proceed as follows:

3. Set all system power switches off.

Installing the TLZ06-AA/BA Cassette Tape Drive 3–1

3.3 Selecting the SCSI Address for the TLZ06-AA/BA Drive
To familiarize yourself with the TLZ06 drive:
1. Refer to Figure 1–2 for the location of the buttons, switches, and connectors
on the TLZ06 drive.
2. Note that all connections are made at the rear of the drive.
Your system uses a SCSI ID switch (Figure 1–2) to identify, or address, the
TLZ06-AA/BA. The SCSI ID is factory set at 0. If you are installing the
TLZ06-AA/BA on a system that is already using SCSI ID 0, use any available
SCSI ID. (You may have to consult your system manager.)
To set/change the SCSI address:
1. Select a unique address number with the first three switches on the right.
2. To set a switch, use a pen (NOT A PENCIL) to push the switch up for OFF
or down for ON.
Table 3–1 shows the SCSI IDs (0 through 7) and Figure 3–1 shows a close-up
view of the switches.
NOTE
If you are installing the tabletop variant, refer to Chapter 2.
Turn off all power before connecting the cables and the terminator.
The drive must be turned off and then on for switch settings to take
effect, or a SCSI bus reset must be received.

NOTE
Make sure that the last SCSI device on the bus is terminated correctly.

CAUTION
If you are using a remote ID cable, you must use the default SCSI ID
of 0.

3–4 Installing the TLZ06-AA/BA Cassette Tape Drive

3.4 Connecting a SCSI Signal Cable — Drive to System
If you are connecting a TLZ06 drive directly to your system, you
should use a SCSI signal cable supplied as part of your system
installation kit.
If you do not have this cable, contact your Digital sales representative. You
should use a cable supplied by Digital Equipment Corporation. Failure to do
so can result in degraded performance of your TLZ06 drive.
To connect a SCSI cable — drive to system — perform the following:
1. Connect one end of the cable to the system SCSI connector.
2. Connect the other end of the SCSI signal cable to the SCSI connector on
the rear of the TLZ06 drive (Figure 1–2).

3.5 Connecting the Power Cable and Mounting
Connect the system internal power cable located at the rear of the drive
(Figure 1–2).
NOTE
Digital service personnel: The power cable disconnects the drive from

5.8 Using the Cassette Tape
Digital Equipment Corporation recommends that you use DDS certified tapes.
The following sections describe how to:
•

Handle and store tape (Section 5.8.1)

•

Write-protect tape (Section 5.8.2)

•

Insert and remove tape (Section 5.8.3)
WARNING
Always place the tape label in the recessed area on the cassette. Never
place one label on top of another label.

NOTE
Use of non-DDS media may result in degraded drive performance. We
recommend the use of Digital Equipment Corporation media.

5.8.1 Proper Handling of Cassette Tapes
To ensure optimal performance from your cassette tapes, observe the following
guidelines when handling them.
•

Avoid placing the cassette tapes near sources of electromagnetic
interference, such as terminals, and video or X-ray equipment. Emissions
from such equipment can erase data on the tape.

•

Keep cassette tapes out of direct sunlight and away from heaters and other
sources of heat.

•

Store cassette tapes (and cleaning cassette) where the room temperatures
are between 5 and 32°C (40 and 90°F).

•

Store cassette tapes in a dust-free environment where the relative humidity
is 20 to 60% RH.

5–4 Using the TLZ06 Cassette Tape Drive

5.8.2 Setting the Write-Protect Tab on the Cassette Tape
If you are using the tape to read or are copying from the tape, set the writeprotect tab to write-protected. This disables writing to tape, and ensures that
data will not be accidentally overwritten. Use a pen (NOT A PENCIL) to set
the write-protect tab (Figure 5–1) to the desired position.
Observe the following guidelines when setting the write-protect tab.
•

If you are reading data (copying from the tape), set the write-protect tab to
write-protected.

•

If you are writing data, set the write-protect tab to write-enabled.

Preventive Maintenance and Problem
Solving
This chapter describes preventive maintenance and problem solving for the
TLZ06 cassette tape drive. Preventive maintenance involves periodic head
cleaning. Problem solving is described in Table 6–1.
Statistics show that over 90% of drive-related problems are associated with the
media. Therefore, Digital Equipment Corporation strongly recommends that
you follow the instructions for handling cassette tapes and cleaning the heads
of the drive.

6.1 Cleaning the Heads
This section shows you how to perform TLZ06 head cleaning. The heads are
the components that physically read and write data to and from the media (in
this case, a cassette tape).
Digital Equipment Corporation recommends that you perform the
head cleaning procedure about every 2 weeks, or after every 50 hours
of drive usage.
Under normal conditions, it should not be necessary to exceed this
cleaning schedule. If a particular data cassette causes problems, try
changing to another data cassette.

Preventive Maintenance and Problem Solving 6–1

CAUTION
Never attempt to clean the heads in a manner other than described
herein. Doing so will void the product warranty.

To clean the heads, use the head cleaning cassette as follows:
1. Press the power switch ON to apply power to the drive.
2. Insert the head cleaning cassette (PN TLZ04-HA) into the drive.
3. With the head cleaning cassette inserted, the drive automatically
executes head cleaning. The drive ejects the head cleaning cassette
after approximately 30 seconds.
4. Locate the card enclosed with the head cleaning cassette. Place a check
mark on the card every time you use the head cleaning cassette.
Under normal conditions, the head cleaning cassette is used for about
25 cleanings. Additional cassettes are available from your Digital sales
representative or DECdirect.
If the head cleaning cassette has been overused, both the Cassette and
the Write-Protect LEDs will flash. Press the eject button to remove the
cleaning cassette. No cleaning action will have occurred.

The TLZ6L auto loader (Figures 7–1, 7–2, 7–3, and 7–4) provides very high
capacity unattended backup, as well as support for the full Random Access
Command Set as defined by SCSI-2. It is packaged in an industry standard
5.25-inch full-high form factor with an embedded TLZ06 tape drive. The
TLZ6L auto loader model is not a field upgrade option for the TLZ06 tape
drive; it must be purchased as a single unit.
With a 4-cartridge magazine, the TLZ6L auto loader provides up to 16
gigabytes of storage. With an 8-cartridge magazine, the TLZ6L auto loader
provides 32 gigabytes of storage; and with a 12-cartridge magazine, it provides
48 gigabytes of storage.

7.2 Indicators
The TLZ6L auto loader has four LED indicators. The labels for these LED
indicators come with the auto loader. They are provided in four languages:
English, French, German, and Spanish; and two orientations: vertical and
horizontal. Choose your labels and place them on the bezel as shown in
Figure 7–1. (The dot matrix display also supports the same four languages.)
The Data Compression LED is lit when data compression is enabled on the
TLZ06 tape drive. Both the Data Compression LED and the LED to its right
flash rapidly when a loader fault occurs. The Reserved LED is reserved for
future use. The Write Protect and Cassette LEDs are described in Chapter 5,

7.4 Operation
The TLZ6L auto loader can be operated two ways: automatically or manually.
It has two modes: Sequential and Random Access.

7.4.1 Automatic Operations
During automatic operations, the TLZ6L auto loader can function in Sequential
and Random Access modes at the same time.
In Sequential mode, upon receipt of a SCSI unload command, the loader
unloads the current cassette and automatically cycles to the next cassette in
the magazine. It continues to unload and cycle to the next cassette until the
last cassette has been unloaded. When this process is complete, the magazine
stops to prevent accidental overwrite of data. Then the magazine may be
unloaded.
In Random Access Mode, the loader responds to all of the SCSI Random Access
Commands.

7.4.2 Manual Operations
Manual operations are performed from the front of the auto loader.
To load a magazine, press the eject button. This opens the drawer and ejects
any magazine that is in the drive. Then place the magazine in the mouth of
the loader until the rollers engage the magazine. The loader automatically
scans the magazine to make sure the cassettes are loaded correctly and to
count the number of cassettes loaded. The loader displays the number of
cassettes loaded. If a 4-cartridge magazine is installed, the drawer closes. If
an 8- or 12-cartridge magazine is installed, the drawer latches in the open
position.
To load a cassette, press the slot button. Press it once to load the first cassette,
twice to load the second cassette, and so on. If you make a mistake, continue
pressing the slot button until the current state is shown on the dot matrix
display. When you press the slot button, the loader displays the selected slot
and allows some time for changes. Then the selected slot is automatically
loaded and the drive becomes ready.
To eject the magazine, press the eject button. This ejects any cassette that is
in the drive, opens the drawer, and ejects the magazine. Then you can remove
the magazine.

7–6 TLZ6L Auto Loader

7.4.3 Single Cassette Operation
If a magazine is in the drive, eject the magazine. When the mouth of the
loader is empty, you can load a single cassette in the drive. The drive should
accept the cassette and load it.
To eject the cassette, press the eject button. The cassette moves into the mouth
of the loader. Then you can remove the cassette.

7.5 Switch Settings

Enabling/Disabling Data Compression
Under ULTRIX and VMS
B.1 ULTRIX TLZ06 Compression and Noncompression
Modes
The default mode for the TLZ06 tape drive is noncompression mode. To use
the TLZ06 tape drive in compression mode, specify the device as:
/dev/rmt?h or /dev/rmt?m
To use the TLZ06 tape drive in noncompression mode, specify the device as:
/dev/rmt?1 or /dev/rmt?a

B.2 ULTRIX DUMP Utility
The parameters that should be used when running the DUMP utility on a
TLZ06 tape drive in compressed and noncompressed mode are as follows:
Noncompressed Mode:
density = 61000 effective tape length (with 90 meter tape) = 57440
Example: dump Odsf 61000 57440/dev/rmt?1/dev/rrz0g
Compressed Mode:
density = 61000 effective tape length (with 90 meter tape) = 57440
compression (which, for most cases is 2)
Example: dump Odsf 61000 114880/dev/rmt?h/dev/rrz0g
NOTE
You must type ULTRIX commands using lowercase characters.
