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. The following subsections introduce the important
technologies that together, comprise the DLT-S4 tape drive system.

The DLT-S4 tape drive system (see figure 1
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.

Chapter 1 Product Information
Tape Drive Design
Tape Drive Design 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
such items as the tape path, tape heads, media, cartridge, and host
interface.
For a detailed description of the integrated drive components, see the
DLT-S4 Product Specification (81-81279-xx).
Table 2 Tape Drive Components
Components Description
Base mechanical
assembly
Front-panel assembly
(bezel)
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 is the mechanism responsible for engaging the media leader on
cartridge load and disengaging 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.
The front-panel assembly (bezel) performs these functions:
• Protects the front of the drive from physical damage
• Channels airflow 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
DLT-S4 Product Manual 6
Chapter 1 Product Information
Tape Drive Design
Components Description
• 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 SDLT technology.
There are three board assemblies:
• Pre-amplifier Board (PAB) — The PAB contains the preamplfier for the read
heads, and the write driver for the write heads.
• Motor Driver Board (MDB) — The MDB interfaces with the reel motor
drivers and hall sensors, actuator driver and sensors, sensor and motor
drives for the soft load, LEDs for front-panel indicators, and eject button
signals.
• Drive Control Board (DCB) — The DCB is the main control card for the DLTS4 tape drive. It sends commands to the MDB to control and drive the tape
mechanism. The board interfaces with the PAB to send signals to the head
for reading and writing.

DLTSage Application Software
DLTSage is a suite of preventative maintenance diagnostic software tools
that enables users to more simply manage tape storage environments. It
1
enhances manageability by allowing you to manage, predict, and prevent
problems that can occur during a routine backup.
DLTSage software is a standard feature of the DLT-S4 tape drive and the
DLTtape S4 cartridge. To learn more about DLTSage, see:
•
www.dltsage.com
• DLTSage and DLTIce User’s Guide (81-81279-xx)

• It provides management protocols for acquiring information on DLT tape drives
and media anywhere on an enterprise network
• It helps you to understand and control how tape drives are used throughout the
system
• It allows you to develop a complete inventory of tape drives and media and the
usage statistics for each
Predict The software continuously monitors usage patterns and then interprets and
analyzes the operational information.
• You can ascertain which cartridges and which tape drives are nearing the end of
their useful lives
• You can predict when the tape drive needs cleaning
• You can use tape drive and cartridge usage statistics to implement predictive
maintenance parameters
Prevent The software allows you to see errors as they happen and correct them instantly.

DLTIce Firmware 1 Quantum’s DLTIce firmware is an extension of the DLTSage architecture.
It acts as the compliance management function of DLTSage. The
firmware allows you to append data to an “iced” cartridge, but you
cannot rewrite, reformat, or erase the data.
This feature uses a Write Once, Read Many (WORM) functionality, which
provides you with the securely archived records that are needed to
achieve government regulatory compliance.
Quantum’s DLTIce firmware is a standard feature of the DLT-S4 tape
drive.
To learn more about DLTIce, see:
•
www.dltsage.com
• DLTSage and DLTIce User’s Guide (81-81279-xx)
Table 4 DLTIce Features
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 10
Chapter 1 Product Information
Tape Drive Design
Feature Description
Identification The identification applies to both the data and the cartridges.
• The storage management software issues a time and date stamp, which enables
you to locate and authenticate specific records using ISV compliant storage
management software
• The cartridge used for DLTIce is a standard DLTtape S4 cartridge. Load the
firmware through DLTSage and use the special yellow labels provided by
Quantum to identify the WORM cartridges
Duplication The data stored on the DLTtape S4 cartridge can be downloaded to another storage
media through any ISV-compliant storage management software.
See “Icing” a Cartridge
on page 91 for instructions on how to create a WORM
cartridge.
DLTtape S4 Cartridge 1 A cartridge is a significant component of any tape drive system. The
DLT-S4 tape drive writes to DLTtape S4 cartridges.
• Color and Pattern — The DLTtape S4 cartridge is and has a
distinctive pattern, in addition to the DLTtape logo, molded in the
plastic.
• Geometry — The cartridge’s geometry is similar to previous DLTtape
cartridges to simplify integration with existing tape library designs,
but has a keying feature to ensure it cannot be loaded into previous
generations of tape drives where writing to the media is
incompatible.
• Debris Resistance — The cartridge is made of wear-resistant
materials to reduce the potential for debris generation and increase
the life of the cartridge.
For more information on cartridges, see appendix A
on page 75.

Ultra320 SCSI Interface 1 The DLT-S4 tape drive conforms to the Ultra320 SCSI standard and
allows for a maximum burst rate of 320 MB per second.
SCSI Stub and Cable Lengths
The longest stub length on the DLT-S4 PCBA is 1.64 inches, and the
maximum cable length for one DLT-S4 tape drive is 20 meters. The
maximum SCSI cable interconnect length is 10 meters total with a
maximum of two DLT-S4 tape drives on the bus.
To operate properly in Ultra320 mode, ensure that all SCSI cables and
terminators are Ultra320 (SPI-4) compatible.
