TLZ09/9L Cassette Tape Device Product
Description
1.1 Overview
The TLZ09/9L Digital Audio Tape (DAT) device provides you with high
capacity, off-line data storage. Depending on the 4 mm data cassette tape used,
the unit can typically store the following amount of data on each tape:
Tape Type (NOTES 1 and 2) No Compression Compression
TLZ04-CA (60 m, DDS-1) 1.3 GB 2.6 GB (see Note 3.)
TLZ06-CA (90 m, DDS-1) 2.0 GB 4.0 GB (see Note 3.)
TLZ07-CA (120 m, DDS-2) 4.0 GB 8.0 GB (see Note 3.)
NOTE
1. The TLZ09/9L is compatible with 60 m cassette tapes written on the
TLZ04 in the noncompressed mode only.
2. The TLZ09/9L is compatible with the TLZ06/6L using 60 m and 90
m tapes only, and with the TLZ07/7L using 60 m, 90 m, and 120 m
tapes.
3. The compression measurements are typical for a 2-to-1 data
compression ratio, but the actual ratio is dependent on the data.
The maximum time to back up (read or write) on a TLZ09/9L 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.
TLZ09/9L Cassette Tape Device Product Description 1–1

1.1.1 System Support
As of this printing, the TLZ09/9L device is supported by a variety of Digital
systems. Consult your Digital Sales Support representative for a list of
supported systems. Your particular system must have an available standard
SCSI (Small Computer System Interconnect) port in order to connect the
TLZ09 or TLZ9L.
1.2 Design Features
The TLZ09/9L cassette tape device uses state of the art technology. The
device’s design incorporates the Digital Data Storage (DDS) recording format
and Digital Audio Tape (DAT) recording technologies. It is also designed to
provide a transfer rate that is twice that of standard DDS-2 DAT drives while
still maintaining full DDS compatibility.
1.2.1 What is Digital Audio Tape (DAT)?
DAT technology provides a high recording density with a very low error rate
through the helical scan recording method. With this method of recording,
both the tape and the recording head move simultaneously. The read and write
heads are located on a rapidly rotating cylinder, or drum that is tilted at an
angle in relation to the vertical axis of the tape. This causes the tracks to be
recorded diagonally across the tape, resulting in an extremely high recording
density, far higher than what is achievable with stationary-head devices.
1.2.2 What is Digital Data Storage (DDS)?
DDS uses a recording format that supports the use of digital audio tape
for computer applications. The objectives of DDS are to maximize storage
capacity and performance, facilitate data interchange, and provide very fast
random access. In addition, this format has three levels of error correction,
which ensures high data integrity. The DDS-DC format, which is a superset
of the basic DDS DAT format, allows you to back up 8 gigabytes of data in
approximately 1.5 hours minimum with no operator intervention, assuming 2:1
compression ratio.
NOTE
Use of non-DDS media may result in degraded drive performance and
is not recommended by Digital Equipment Corporation.
1–2 TLZ09/9L Cassette Tape Device Product Description

1.2.3 What is the Media Recognition System (MRS)?
MRS refers to a series of alternate opaque and clear stripes at the beginning
of a tape. This striping is used to classify the media as data grade rather than
audio grade media. Use of MRS helps to ensure that only data grade tapes are
used in computer applications. All 120-meter cartridges support MRS. Shorter
media are available in both MRS and non-MRS types.
1.3 TLZ09/9L Models
The TLZ09 drive is available in several configurations:
• Model TLZ09-DA/DB (tabletop) — a compact external unit with a built-in
power supply and fan (Figure 1–1).
• Model TLZ09-AA/AB — a 3 1/2-inch, half-height drive that mounts
internally (Figure 1–2 and Figure 1–4).
• Model TLZ09-BA/BB—a31/2-inch drive in a 5 1/4-inch, half-height
form factor allowing the drive to be mounted internally (Figure 1–3 and
Figure 1–4).
• Model TLZ09-VA — a TLZ09-AA mounted in a 3 1/2-inch StorageWorks
SBB.
• Model TLZ09-AX — a field spare unit that is configurable to an -AA, -AB,
-BA, or -BB model. Includes bezel and rail installation procedures.
NOTE
All the models have a drive buffer size of 1 MB of memory.
The TLZ9L autoloader is available in several configurations:
• Model TLZ9L-AA — a 5 1/4-inch, full-height autoloader that mounts
internally (Figure 7–1). This unit comes with a light gray (DEC 217) bezel
installed and a dark gray (DEC 277) bezel in the shipping carton, along
with bezel removal/mounting procedures.
• Model TLZ9L-DA/DB (tabletop) — an external unit with a built-in power
supply and fan (Figure 7–2).
• Model TLZ9L-VA/VB — a TLZ9L-AA mounted in a 5 1/4-inch StorageWorks
SBB.
