Tape Drive Technology

Tape Drive Technology 1

The DLT-S4 tape drive incorporates state-of-the-art technologies that
contribute to the SDLT architecture. Some of these ideas are trademarked,
others are patented. Table 2
comprise the DLT-S4 tape drive system.

Table 2 Tape Drive Technology

Technology Description

lists some of the important technologies that

Laser Guided
Magnetic Recording

Magneto Resistive
Cluster Heads

Advanced Partial
Response Maximum
Likelihood

Advanced Metal
Powder Media

Positive Engagement
Tape Leader
Buckling Mechanism

The DLT-S4 tape drive system is based on Quantum’s Laser Guided Magnetic
Recording (LGMR) technology. LGMR provides a unique combination of the
best optical and magnetic technologies, which results in dramatically higher
capacities by substantially increasing the number of recording tracks on the
data-bearing surface of the media.

Magneto Resistive Cluster (MRC) heads are a densely packed array of small
Magneto Resistive (MR) tape heads precisely positioned using advanced thin­film processing technology.

Improving on Partial Response Maximum Likelihood (PRML) technology
traditionally used in disk drives and communication systems, Quantum’s
advanced PRML channel technology, co-developed with Lucent Technologies,
brings new levels of performance and capacity to high-performance linear tape
products.

Advanced Metal Powder (AMP) media is a state-of-the-art media using
durable metal powder technology for recording high densities of data. The
back side of AMP media receives a specially formulated coating to accept the
optical servo tracks, which ensures that the entire data-bearing side of the
media is available for recording data and eliminates the need for pre­formatting.

The positive engagement tape leader buckling mechanism engages the media
leader on cartridge load and disengages it on cartridge unload. It uses a metal
pin attached to the tape drive leader to link with molded clips permanently
attached to the media leader inside the cartridge.

DLT-S4 Product Manual 7

Chapter 1 Product Overview

Tape Drive Components

Tape Drive Components 1

The DLT-S4 tape drive is designed as a total system. The system includes
a complex interaction of a number of important components including
the base mechanical assembly, the front panel assembly (bezel), and the
board assemblies. Table 3

Table 3 Tape Drive Components

Components Description

describes these components.

Base mechanical
assembly

The base mechanical assembly houses the tape control mechanical, actuator,
reel motor, load mechanism, eject button, and front-panel indicators. It
positions the actuator servo head over the correct tape track. It implements the
functions required to buckle and unbuckle the media and control the media
motion. It engages the media leader on cartridge load and disengages it on
cartridge unload.

• Auto load—The tape auto load is a soft-load and seating mechanism that is
tolerant of forced media loading; a media sensor is triggered upon cartridge
insertion, and after the media reaches a hard stop point, the auto load sensor
engages, pulling the cartridges the remaining distance onto the motor. On
media ejection, the assembly reverses the process and automatically ejects
the cartridge a fixed distance from the front of the tape drive.

• Base plate—Acts as the support platform for the other modules and for the
tape drive enclosure. It also includes the mounting holes (shock mounts)
used to install the tape drive into a server or tape library.

DLT-S4 Product Manual 8

Components Description

Chapter 1 Product Overview

Tape Drive Components

Front panel assembly
(bezel)

The front panel assembly (bezel) performs these functions:

• Protects the front of the drive from physical damage

• Channels air flow through the system

• Aligns the cartridge when it is inserted into the system

• Provides label identifiers for the LEDs mounted on the front of the tape
drive

• Enables cartridge ejection

• Reduces internal environmental contamination with a built-in dust door
(internal and tabletop configurations only)

Board assemblies The board assemblies provide the main control function for the system and the

interface from the system to the host computer, library, or autoloader. This
provides the Advanced Partial Response Maximum Likelihood (PRML) feature
of the Quantum DLT-S technology.

There are three board assemblies:

• Pre-amplifier Board (PAB) — The PAB contains the preamplfier for the read

• Motor Driver Board (MDB) — The MDB interfaces with the reel motor
drivers and hall sensors, actuator driver and sensors, sensor and motor
drivers for the soft load, LEDs for front-panel indicators, and eject button

installed or attached before installing or removing the tape drive to
prevent the possibility of electrical shock or damage to the tape drive.

• Unplug the system that contains—or is to contain—the tape drive
from AC power before installing the tape drive to provide an added
measure of safety.

• Read, understand, and observe all label warnings.

DLT-S4 Product Manual 14

Chapter 2 Before You Begin

Tape Drive Handling and Storage Guidelines

• The DLT-S4 tape drive uses a Class I laser product. This laser product
complies with 29 CFR 1200 and 29 CFR 1910 as applicable on the date
of manufacture.

Warning: If you open the tape drive chassis, you may become

exposed to invisible laser emission which could be
harmful if you are directly exposed to the beam.

Tape Drive Handling and Storage Guidelines 2

Damage to the DLT-S4 tape drive system can occur as the result of
careless handling, vibration, shock, or electrostatic discharge (ESD). For
more details on ESD, see Electrostatic Discharge Protection

Follow these guidelines to avoid damage to the tape drive:

Caution: Never power off the tape drive or the host while the tape

drive contains a cartridge. Failure to remove a cartridge
may result in cartridge or tape drive damage.

on page 16.

• Always handle the tape drive carefully and gently— a drop of ¼ inch
onto a bench or desktop can damage a tape drive.

• Hold the internal tape drive only by its sides.

• Never hold or carry the tape drive by inserting your fingers into the
receiver area on the front of the tape drive. You could damage the
receiver area if you lift or carry it in this manner.

• Do not bump, jar, or drop the tape drive. Use care when transporting
the tape drive.

• Do not place the tape drive so that it rests on its front bezel.

• Always gently place the tape drive flat and horizontal on an
appropriate ESD-protected work surface to keep the tape drive from
accidentally being knocked over.

• Do not stack objects on the tape drive.

DLT-S4 Product Manual 15

Chapter 2 Before You Begin

Electrostatic Discharge Protection

• Do not expose the tape drive to dusty, humid, or smoke-filled areas,
or to excessive heat or cold (see Physical Specifications
required temperature and humidity conditions).

• Do not place foreign objects inside the tape drive’s receiver area (see

figure 4

).

on page 38 for

Figure 4 Receiver Area

Electrostatic Discharge Protection 2

Several electrical components of the DLT-S4 tape drive system are
sensitive to static electricity and electrostatic discharge (ESD). Even a
static buildup or discharge that is too slight to feel can be sufficient to
destroy or degrade a component’s operation.

To minimize the possibility of ESD-related damage to the system, the
tape drive’s manufacturer strongly recommends using both a
workstation anti-static mat and an ESD wrist strap. If the devices are
correctly installed and properly used, they reduce the buildup of static
electricity that might harm the system.

Follow these guidelines to avoid ESD damage to the tape drive:

• Use a properly fitted wrist strap or other suitable ESD protection.

• Observe proper ESD grounding techniques.

• Keep the internal tape drive in its antistatic bag until ready to install.

DLT-S4 Product Manual 16

Chapter 2 Before You Begin

Pre-Installation Guidelines

• Place the tape drive in the antistatic bag before placing it in a
shipping container.

• Hold the internal tape drive only by its sides.

• Place the tape drive on a properly grounded anti-static work surface
pad while it is out of its protective antistatic bag.

• Do not pack other materials with the tape drive in its antistatic bag.

• Do not use the bag as a substitute for the work surface antistatic pad.
The outside surface of the bag may not have the same antistatic
properties as the inside surface. It could actually increase the
possibility of ESD problems.

• Do not remove either the tabletop tape drive cover or the internal/
library tape drive cover to use any test equipment to check
components on the PCBAs. There are no user-serviceable
components on the tape drive.

Pre-Installation Guidelines 2

Before you install the tape drive in a system, follow these steps. Also,
check the tape drive to be certain it is operating properly before installing
it in a system.

1 Unpack and review the contents of the box for any physical damage.

If you find damaged items, contact the tape drive sales representative
and the shipping company immediately.

2 Save the shipping box and packing materials in case you need to

move or ship the tape drive at a later date.

Caution: When returning a unit to Quantum for repair, you

must use the original or equivalent packing materials
or risk voiding your warranty.

3 Record the model and serial number of the DLT-S4 tape drive system

in the space provided below.

Choosing Compatible Cartridges

The DLT-S4 tape drive can read from, but not write to:

• Super DLTtape II cartridges formatted in the SDLT 600 tape drive

• Super DLTtape I cartridges formatted in the SDLT 320 tape drive

The DLTtape S4 cartridge is black and has a distinctive pattern molded
into the plastic, along with the DLTtape logo. The cartridge is made of
wear-resistant materials to reduce the potential for debris generation and
increase the life of the cartridge.

The cartridge’s geometry is similar to previous DLTtape cartridges to
simplify integration with existing tape library designs (see figure 5

). Its
keying feature, however, ensures that it cannot be loaded into previous
generation tape drives.

Using Unsupported Cartridges

Using Unsupported Cartridges 3

DLT-S4 tape drives are intended to be used only with the cartridges
specified in Choosing Compatible Cartridges
Quantum DLT drives are tested with a variety of unsupported cartridges
and are designed to ensure that no damage occurs to either the tape drive
or the cartridge if a user attempts to use an unsupported cartridge.

If you try to insert an unsupported cartridge into the DLT-S4 drive, the
drive will not be able to accept it. Possible results are:

• You may not be able to insert the unsupported cartridge into the

drive.

• The unsupported cartridge may trigger the soft-load mechanism at

an inappropriate time, which may cause the soft-load mechanism to
stop at an improper location. While the soft-load mechanism is
stopped, the unsupported cartridge may not be completely loaded in
the drive, and the drive may not automatically eject the cartridge. (If
this happens, you must manually eject the cartridge by issuing an

EJECT command or by pressing the Eject button.)

Cartridge Handling and Storage Guidelines

Cartridge Handling and Storage Guidelines 3

DLTtape S4 cartridges are engineered to be reliable, robust, and durable.
They are manufactured to withstand 1,000,000 head passes and have a
shelf life of 30 years. By following these guidelines, you will greatly
reduce the chance that you will experience problems with the cartridges
or cause damage to the tape drive system.

Caution: The safety of data depends on proper care and handling of

cartridges.

Caution: Never power off the tape drive while it contains a

cartridge. Failure to remove a cartridge prior to power-off
may result in cartridge or tape drive damage.

For best results, follow these guidelines for data cartridge handling and
storage:

• Follow the handling instructions and observe the environmental

specifications provided in the plastic cartridge case.

• Inspect tape cartridges for damage as described in Inspecting a

Cartridge on page 25.

• Store cartridges vertically in their protective cases when not in use or

when archived (see figure 6

• Protect cartridges from shock, vibration, moisture, direct sunlight,

dust, smoke, and magnetic fields.

• Do not stack more than five cartridges on top of each other.

• Do not carry cartridges loosely in a box or any other container.

Allowing cartridges to jostle together exposes them to unnecessary
physical shock.

• When carrying cartridges in their cases, orient the cases so that the

grooves in the cases interlock. This prevents the cases from slipping
apart and falling.

• Do not drop the cartridge. A dropped cartridge may have dislodged,

loosened, or damaged internal components. If you drop a cartridge,
give it a thorough visual inspection (see Inspecting a Cartridge
page 25 for complete instructions).

DLT-S4 Product Manual 23

).

on

Chapter 3 Cartridges

Cartridge Handling and Storage Guidelines

• Use only the slide-in labels provided with each cartridge or slide-in

bar code labels designed for use with DLT media. Slide labels into the
label slot on the cartridge (see figure 6

). Never apply adhesive labels
or “sticky” notes on the top, side, or bottom of tape cartridges, and do
not write on the cartridge.

• Do not write on the labels with debris-producing writing
instruments, such as graphite pencils and water-soluble felt pens.

• Other than the bar code label, ensure that nothing else is stuck to the
cartridge before inserting it into the tape drive. Loose labels and other
materials can cling to the bottom of the cartridge and get stuck in the
tape drive.

• Leave unused labels attached to the printed material (called the
u-card) within the cartridge case.

• Store any loose labels or other materials that are smaller than 4.5 x 4.5
inches (114.3 x 114.3 mm) separate from the cartridge. A loose label or
piece of paper accidentally inserted into the tape drive along with a
cartridge can prevent the hub reel and tape drive gear from meshing.

• Never touch the tape or media leader. Dust and oils from your skin
contaminate the tape and affect performance.

• Avoid unnecessarily opening the cartridge media access door (see

figure 9

). This may expose the media to contamination or physical

damage.

• Protect cartridges from shock, vibration, moisture, direct sunlight,
dust, smoke, and magnetic fields. Devices that may produce
magnetic fields, such as computer monitors, motors, or video
equipment can alter or erase data on the media.

• Observe the proper temperature and humidity conditions for
operating and storing cartridges as follows:

Temperature

Operating 10 °C to 40 °C (50 °F to 104 °F)
Storage (with data) 18 °C to 28°C (64 °F to 82 °F)

Humidity

Operating 20% to 80% non-condensing
Storage (with data) 40% to 60% non-condensing

Note: If storage or transportation of a cartridge has exposed it to

temperature or humidity conditions outside the
specifications shown in the preceding table, allow the
cartridge to acclimate to the proper operating environment
for 24 hours before using it.

Store data cartridges vertically in
plastic cases

Use slide-in labels

Inspecting a Cartridge 3

Improper cartridge handling is the primary reason for tape drive
problems. To avoid losing data or damaging the tape drive, inspect the
cartridges:

• Before loading a new cartridge in the tape drive

• After dropping a cartridge or subjecting it to physical shock

DLT-S4 Product Manual 25

Chapter 3 Cartridges

Inspecting a Cartridge

• When the tape drive becomes inoperable after loading a cartridge

• When you receive a shipment of cartridges that show any sign of
shipping damage

Follow these steps to inspect a tape cartridge:

1 Gently shake the cartridge and listen for loose pieces.
2 Remove the cartridge from its protective plastic case.
3 Check for loose debris attached to the cartridge, and for other

contamination (oily, slimy, or sticky substances) that may have built
up on the surface of the cartridge.

4 Check the cartridge for any obvious cracks or other physical damage.

Rotate the cartridge in your hands, looking for broken or missing
parts.

5 Rotate the cartridge to view the bottom (see figure 7).

Confirm that the spring-loaded hub on the bottom of the cartridge is
centered. Press the hub to ensure that the spring is functioning
properly and that the hub returns to its normal position.

Caution: If a cartridge shows any signs of damage, do not use it.

).

If a cartridge is dropped, retrieve the data, back it up
on a new cartridge, and dispose of the dropped
cartridge. A dropped cartridge should not reused even
if it shows no signs of damage.

Write-protecting a Cartridge 3

Each cartridge has a write-protect tab, which you can use to prevent
accidental erasure of data. Before inserting the cartridge into the tape
drive, position the write-protect tab on the front of the cartridge (see

DLTSage WORM 3

DLTSage WORM is the firmware compliance management function of
DLTSage. This feature uses a Write Once, Read Many (WORM)
functionality, which allows you to securely archive data stored on a
DLTtape S4 cartridge written on a DLT-S4 tape drive. The firmware
allows you to append data to a cartridge, but you cannot rewrite,
reformat, or erase the data.

DLTSage WORM firmware is a standard feature of the DLT-S4 tape drive
and the DLTtape S4 cartridge. See Formatting a Cartridge as DLTSage

WORM on page 35 for instructions on how to create a WORM cartridge.

DLTSage WORM Features 3 This section details the many features of DLTSage WORM. For more

information, see

http://www.dlttape.com/technology/DLTSageWORM/index.aspx

Feature Description

Security The tape drive’s firmware places an electronic signature key on each cartridge to

ensure that data written to the media cannot be rewritten, reformatted, or erased.

• The key is a unique identifier that cannot be altered.

• The firmware allows you to append new data to the cartridge.

• The cartridge initialization process assures that only unformatted cartridges will
be WORM enabled.

Verification The verification is a two-part process.

• The DLT-S4 tape drive provides best-of-class verification through its ECC
algorithms.

• The firmware provides archive media verification and tamper verification with
time and date signatures.

DLT-S4 Product Manual 34

DLT-S4 Product Manual 57

Chapter 7 Fibre Channel Interface

Practical Considerations

Practical Considerations 7

This section describes considerations specific to the DLT-S4 Fibre
Channel tape drive.

Hot-Swappable Cables 7 Fibre Channel cables are “hot swappable,” which means that you may

connect and disconnect them with unit power turned on. Therefore,
unlike some other systems, the tape drive and computer may remain
powered on while you connect the DLT-S4 tape drive to the host
computer.

Power Usage 7 DLT-S4 Fibre Channel tape drives use slightly more power than SCSI-

configured tape drives. See the DLT-S4 Product Specification (81-81279-xx).

Power Cycle (Tape Drive On)

Failure to Obtain a Loop Address

DLT-S4 Product Manual 58

When the tape drive completes the power cycle process (including POST)
and the port is initialized, the Fibre Channel port is enabled and will

7

attempt to initialize on the attached Fibre Channel topology.
When the tape drive completes the power cycle process (tape drive

turned on and POST complete), the device is on-line and capable of tape
drive operations.

See Power-On Self-Test

If the tape drive is unable to obtain an address (fabric assigned,
previously assigned, hard assigned, or soft assigned), it goes into a non-

7

participating mode and immediately implicitly logs out all logged-in
ports.

If the tape drive experiences a power-on reset, or recognizes an
LIP (AL_PD, AL_PS), it does not retain a previously acquired address to
use during the next loop initialization.

on page 113 for information about POST.

Chapter 7 Fibre Channel Interface

Fibre Channel Speed and Topology

Fibre Channel Speed and Topology 7

Although Fibre Channel DLT-S4 tape drives will auto-negotiate the speed
and topology, you may override the automatic selections by placing
jumpers on the Fibre Channel jumper block at the rear of the tape drive.

If you decide it is necessary to change the tape drive’s speed or topology,
use your fingers to move the jumpers to the pattern corresponding to the
speed or topology you want. Using this jumper block is optional.

Figure 19 Fibre Channel
Speed and Topology Jumper
Block

Note:

See:

• Figure 17

• Figure 19

• Table 32

The tape drive only checks the jumpers at a power cycle. To
change the speed or topology configurations after installation,
turn off the tape drive, move the jumpers as needed, and then
turn on the tape drive.

Chapter 9 Installing an Internal SCSI Tape Drive

Unpacking the Tape Drive

Unpacking the Tape Drive 9

Before you begin, clear a desk or table so that you can unpack the tape
drive.

Note: If the room in which you are working differs from the

temperature at which the tape drive was shipped or stored by
30 ºF (17 ºC) or more, let the tape drive acclimate to the
surrounding environment for at least 12 hours before opening
the shipping carton.

Unpack and inspect the tape drive for shipping damage. If you notice any
damage, report it both to the sales representative and to the shipping
company immediately.

Caution: Save the packing materials in case you need to move or

ship the tape drive in the future. When returning a unit to
Quantum for repair, you must use the original or
equivalent packing materials or risk voiding your
warranty.

If there is no damage to the tape drive, select a server or workstation to
host the tape drive, then move on to the following installation steps.

Setting the SCSI ID 9

Each device on the SCSI bus must have a unique SCSI ID address
assigned to it. Check the SCSI IDs on all other devices on the selected
server or workstation, including the SCSI host adapter, and select an
unused SCSI ID for the tape drive. The factory default SCSI ID for the
internal tape drive is 5 (no jumpers are installed on the jumper block). If
the tape drive’s factory default SCSI ID is not currently in use by another
device, you do not need to change the SCSI ID.

Caution: If you reset the SCSI ID, do not use ID 7, as that ID is

already in use by the SCSI host adapter.

Chapter 9 Installing an Internal SCSI Tape Drive

Securing the Tape Drive in the System

Note: The computer system and the tape drive SCSI IDs are only

checked when you turn both the computer system and the
tape drive off and then on again. To change the SCSI ID after
installation, turn off the system, change the tape drive’s SCSI
ID, and then turn on the system.

Securing the Tape Drive in the System 9

This section describes how to mount and secure the tape drive in the
system. Because of the variety of mounting possibilities for tape drives,
the instructions presented here are general guidelines. Use these
instructions only as a guide for mounting the tape drive in the system.

Note: In some system configurations, it may be more convenient to

connect the SCSI bus and power cables to the tape drive before
securing it in the system.

Mount the tape drive in the system by performing the following steps:

1 Ensure that the host computer and all peripheral devices are turned

off.

2 Position the tape drive in the system and align the tape drive

mounting holes (side or bottom) with those in the system (see

figure 24

3 Secure the tape drive in the bay or chassis using four M3 x 8mm long

and figure 25).

screws.

Caution: The screws used to mount the tape drive must be

M3 x 8mm long. This kind of screw is exactly the
proper length and will not damage the tape drive.

Connecting the Cables and Terminating the SCSI Bus

Connecting the Cables and Terminating the SCSI Bus 9

You can connect the DLT-S4 tape drive to the host computer as a single
device, or as one of two total devices connected via a SCSI cable with
multiple SCSI connectors in a “chain” configuration.

If you are connecting two devices to the SCSI bus, connect only one tape
drive to the host computer at this time. Finish the installation procedure
and confirm that the host computer and tape drive are communicating
correctly (see Confirming the Installation
device (see Adding an Additional Device

Follow these steps to connect the tape drive to the host computer (see

Caution: Never connect the tape drive while the tape drive,

host system, or peripheral devices are turned on.
Doing so could result in damage to the tape drive or
other peripheral devices.

2 Disconnect any other SCSI devices from the SCSI bus at this time.

You can add them back on later (see Adding an Additional Device

Connecting the Cables and Terminating the SCSI Bus

If the SCSI cable you are using has a built-in terminator, you do not
need to add another terminator (see figure 26

for an example of such
a cable). If the cable is not terminated, then install an active Ultra320
SCSI terminator on the SCSI cable (see figure 27

).
