Overview
The Quantum A-Series Tape Drives are an extension to the family of
products with video professionals in mind. Using the built-in FTP client
in conjunction with a standard Web browser, Material Exchange Format
(MXF) files can be stored and retrieved. A Gigabit Ethernet (GigE)
interface allows these drives to be quickly connected and accessed on
your network.
The A-Series tape drives are ideal for serving a full range of video
applications; from hand-carrying video content out to a truck for live
production to facility-wide, long-term, secure archive.

Java Plug-in
The A-Series tape drive utilizes a Web-based interface allowing you to
manage the tape drive from a remote workstation on the same network.
The tape drive is configured and managed through Web pages accessible
by Internet browser software installed on the host computer.

Resetting System Defaults
Resetting System Defaults
As there is no access to the A-Series tape drive other than the Ethernet
port, a mechanism has been implemented to reset the settings to their
default values. This is useful if an end user loses the IP address of the
A-Series tape drive. The settings can all be set up through the Web
manager (i.e. IP settings, root password, ...).
To have the settings set back to their default values:
1 Switch off your tape drive.
2 Disconnect the network cable from the drive.
3 Repeat the following procedure three times:
aInsert a write protected cartridge into the drive.
bSwitch on the tape drive.
cAfter approximately one minute, the cartridge will be ejected.
dSwitch off the drive.

Warranty Note
Chapter 2 Getting Started
Warranty Note
See the warranty before installing your tape drive. Certain actions taken
during installation could void the warranty if not properly conducted.
Generally, the Limited Product and Limited Repair Warranties are
contingent upon proper use in the application for which the product is
intended; and do not cover the product if you perform any of the
following actions:
• Modify the product without the manufacturer’s written approval.
• Subject the product to unusual physical, environmental, or electrical
stress, including damage caused by handling or shipping in
unapproved containers or packaging.
• Disturb any warranty labels, or the integrity of the product in any
other way.
• Remove or damage the serial number label to the extent that
warranty status of the product cannot be determined.
Safety, Handling, and ESD Protection
Inappropriate or careless handling of the A-Series tape drives may result
in damage to the product. Follow the precautions and directions to
prevent damaging the tape drive.
Safety Precautions2
Quantum A-Series Tape Drives User’s Guide9
For your safety, follow all safety procedures described here and in other
sections of the manual.
1 Power off the system before installing or removing the tape drive to
prevent the possibility of electrical shock or damage to the tape drive.
Unplug the unit that contains—or is to contain—the tape drive from
AC power to provide an added measure of safety.
2 Read, understand, and observe all label warnings.
Chapter 2 Getting Started
Safety, Handling, and ESD Protection
3 The Pivoting Optical Servo (POS) 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.
Handling2
Damage to the tape drive can occur as the result of careless handling,
vibration, shock, or electrostatic discharge (ESD). For more details about
ESD, see Electrostatic Discharge Protection
.
Caution:Always handle the A-Series tape drive with care to avoid
damage to the precision internal components. Hold the
tape drive only by its sides. Never hold the tape drive by
inserting fingers into the receiver area on the front of the
tape drive. Damage to the receiver area may occur if you
lift or carry it in this manner.
Follow these guidelines to avoid damage to the tape drive:
• Always observe prescribed ESD precautions.
• Keep the external tape drive in its anti-static bag until ready to install.
• Always use a properly fitted wrist strap or other suitable ESD
protection when handling the tape drive.
• Hold the tape drive only by its sides.
• Do not bump, jar, or drop the tape drive. Use care when transporting
the tape drive.
• Always handle the tape drive carefully and gently. A drop of ¼ inch
onto a bench or desktop may damage a tape drive.
• Never place the tape drive so that it rests on its front bezel. Always
gently place the tape drive flat, bottom side down, on an appropriate
ESD-protected work surface to avoid the tape drive being
accidentally knocked over.
• Do not pack other materials with the tape drive in its anti-static bag.
• Place the tape drive in the anti-static bag before placing it in a
shipping container.
• Do not stack objects on the tape drive.
Quantum A-Series Tape Drives User’s Guide10
Chapter 2 Getting Started
Safety, Handling, and ESD Protection
• Do not expose the tape drive to moisture.
• Do not place foreign objects inside the tape drive’s receiver area.
Electrostatic Discharge
Protection2
Several electrical components of the A-Series tape drive 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
drive’s manufacturer strongly recommends using both a workstation
anti-static mat and an ESD wrist strap. When correctly installed and
properly used, these devices reduce the buildup of static electricity that
might harm the system.
Observe the following precautions to avoid ESD-related problems:
• Leave the tape drive in its anti-static bag until you are ready to install
it in the system.
• Always use a properly fitted and grounded wrist strap or other
suitable ESD protection when handling the tape drive and observe
proper ESD grounding techniques.
• Hold the tape drive only by its sides.
• Place the tape drive on a properly grounded anti-static work surface
pad when it is out of its protective anti-static bag.
• Do not use the bag as a substitute for the work surface anti-static pad.
The outside surface of the bag may not have the same anti-static
properties as the inside surface. It could actually increase the
possibility of ESD problems.
• Do not remove covers to use any test equipment to check components
on the PCBAs. There are no user-serviceable components on the tape
drive.

Data Cartridge Care and
Maintenance3
Observe the following precautions to protect your data:
Always:
• Remove the cartridge from the drive when not in use
and store it in its protective case.
• Avoid dropping the cartridge. This can damage
components inside the cartridge, possibly rendering
the tape unusable. If you drop a tape cartridge, open
the cartridge door and make sure that the leader pin
is in the correct position.
• Re-tension a dropped cartridge before using.
• Keep the cartridge away from:
• Direct sunlight and heat sources, such as
radiators, heaters, or warm air ducts.
• Sources of electromagnetic fields, such as
telephones, computer monitors, dictation
equipment, mechanical or printing calculators,
motors, magnetic tools, and bulk erasers.
Do not:
• Expose the cartridge to dirt, dust or moisture.
• Touch the tape media within the cartridge.
• Bulk erase Ultrium tape cartridges. LTO tape
cartridges have prewritten servo patterns that
cannot be reformatted by the tape drive. A bulk
erase operation would make them unusable.
• Use tape cartridges outside the specified operating
conditions: 10
o
C to 40o C, 20% to 80% relative
humidity.
If a tape cartridge has been exposed to conditions
outside the specified range, recondition the tape
before using in the operating environment by
exposing it to the operating environment for a time
equal to or greater than the time it was outside the
operating environment, up to a maximum of 24
hours. Then re-tension the tape to stabilize the tape
pack for better performance.

tape drive is not mounted in a tape automation library, the tape ejects.)
If the tape drive is mounted in a tape automation library, the data
cartridge rewinds to BOT and unbuckles in preparation for unloading,
but does not automatically eject.

A-Series SDLT 600A Tape Drive
The SDLT 600A tape drive incorporates various new 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
SDLT 600A tape drive.
A-Series SDLT 600A Tape Drive
Laser Guided Magnetic
Recording1
Pivoting Optical Servo 1
Magneto Resistive
Cluster Heads1
The SDLT 600A tape drives are based on 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. By recording data
magnetically on the data-bearing side of the media and using servo
movement optically on the backside, LGMR optimizes highly proven
technologies to deliver the most efficient, reliable, and scalable data
retrieval solution to the mid-range market.
Pivoting Optical Servo (POS) is a Quantum-invented, optically-encoded
servo system, that combines high-density magnetic read/write data
recording with laser servo guiding. The POS provides high-duty-cycle
applications, which decreases cost and increases user convenience. The
POS enables the head to track dynamic variations in tape motion which
allows Quantum to provide a track count with an order of magnitude
increase over previous products.
Magneto Resistive Cluster (MRC) heads are a densely packed array of
small, cost-effective Magneto Resistive (MR) tape heads precisely
positioned using advanced thin-film processing technology. SDLT MRC
heads provide high wafer usage efficiency resulting in low head costs, are
less susceptible to variations in tape speed, yield higher track density and
capacity, and provide a multi-channel architecture for increased transfer
rate and performance.
Improving on Partial Response Maximum Likelihood (PRML) technology
traditionally used in disk drives and communication systems, advanced
PRML channel technology, co-developed with Lucent Technologies,
brings new levels of performance and capacity to high-performance
linear tape products. This provides high-encoding efficiency recording
densities for greater capacity and performance that enables SDLT to
increase transfer rates and capacity substantially.
Advanced Metal Powder (AMP) media is a state-of-the-art media using
durable metal powder technology for recording very high densities of
data. The back side of the AMP media receives a specially formulated
coating to accept the optical servo tracks. Because the servo information is
on the back side of the media, the entire data-bearing side of the media is
available for recording data and eliminates the need for pre-formatting.
In addition, AMP media meets the needs of multiple generations of the
SDLT technology.
The positive engagement tape leader buckling mechanism is a highly
robust mechanism that increases data cartridge life and supports the
extensive duty-cycle environments found in high-end and automation
environments.
This mechanism engages the tape leader upon data cartridge load and
disengages it upon data cartridge unload. It uses a solid metal pin
attached to the drive leader to link with molded clips permanently
attached to the tape leader inside the data cartridge. The Positive Leader
Link design makes the buckling of Super DLTtape media a totally reliable
mechanical process.
Modular Design
The SDLT 600A 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, data cartridge,
and host interface.

Modular Design
As shown in figure 10, the SDLT 600A tape drive consists of five distinct
modules:
•Data Control Module (DCM)
•Tape Control Module (TCM)
•Front Panel Module (FPM)
•Electronic Interface Module (EIM)
•Super DLTtape II Data Cartridge (Data Cartridge).
The modular concept makes the SDLT 600A tape drive easy to
manufacture and configure. Each module is optimized to perform a
specific set of functions and designed to interface with the other modules
in a well defined and flexible manner.
The following subsections provide a brief overview of each module.
Note:Despite the deliberate modularity of each module, with the
exception of the FPM, individual users should not
swap
modules. The FPM is the only module that is field replaceable.
Customer adjustments to the TCM, DCM, or EIM will void the
tape drive’s warranty.
Quantum A-Series Tape Drives User’s Guide30

Data Control Module1
Tape Control Module1
The Data Control Module (DCM) contains several of the functions and
features of LGMR technology, which is at the heart of the SDLT
technology. Of the five technologies that constitute the LGMR
technology, two are in the DCM. These are the POS and the MRC heads.
The main functions of the DCM are to provide the path and guides for all
tape motion inside the tape drive and to write data to and read data from
the tape. In addition to the POS and MRC heads described in Pivoting
Optical Servo and Magneto Resistive Cluster Heads, the DCM contains a
number of components that interact to perform these functions. These
components include:
•Advanced head guide assembly
•Take-up reel
•Drive motor
•Optical servo system
•Tape heads.
In addition to its mechanical components, the DCM also contains printed
circuit boards that control the functions of the DCM and the tape heads.
The Tape Control Module (TCM) implements the functions required to
buckle and unbuckle the tape and control the tape motion. The TCM
consists of a variety of components:
The TCM has its own PCBA that controls the functions of the TCM and
interfaces with the main controller board in the EIM. By designing the
TCM as a distinct module, it allows manufacturing and testing the TCM
Quantum A-Series Tape Drives User’s Guide31

Modular Design
as a stand-alone module, simplifying the design, manufacturing, and
troubleshooting processes.
Base Plate
The SDLT 600A tape drive base plate is an aluminum die casting with
precisely machined surfaces. The casting acts as the support platform for
the other modules and for the tape drive enclosure. The base plate also
includes the precision mounting holes used to install SDLT 600A tape
drives into a server or tape library. The SDLT 600A tape drive base plate,
and therefore the entire SDLT 600A tape drive, conforms to the 5.25 inch,
full-height form factor.
Data Cartridge Receiver
On tape insertion, the data cartridge receiver assembly guides the tape
into its operating position, opens the data cartridge door, unlocks the
data cartridge brakes, engages the data cartridge drive motor, and
secures the tape for operation. On tape ejection, the data cartridge
receiver assembly reverses the process and automatically ejects the tape a
fixed distance from the front of the tape drive.
The Front Panel Module (FPM) of the system (sometimes referred to as
the bezel) performs a number of functions:
•Protecting the front of the TCM from physical damage
•Channeling airflow through the system
•Aligning the data cartridge when it is inserted into the system
•Providing system status and information through LEDs
•Enabling data cartridge ejection
Modular Design
•Delivering the overall cosmetic look of the system.
The FPM is a single module with lenses for the system’s LEDs and a
button to activate the drive eject switch. The SDLT 600A tape drive front
panel contains no electronics.
Electronic Interface
Module1
Super DLTtape II Data
Cartridge1
The Electronic Interface Module (EIM) is the electronic heart of the tape
drive. It provides the main control function for the system and the
interface from the system to the host computer, library, or autoloader.
The EIM provides the Advanced PRML feature of Quantum’s SDLT
technology. See Advanced Partial Response Maximum Likelihood
on
page 29 for a brief description of PRML.
The EIM consists of two major boards: the Integrated Controller Module
(ICM), and a separate Host Interface Module (HIM), see figure 10
. The
ICM contains the main controller and servo microprocessor, the customdesigned SDLT ASICs, and the cache memory while the HIM implements
the interface between the host system and the tape drive. This allows easy
configuration of the tape drive to match different host interfaces by
simply substituting the appropriate HIM card.
As with the other major modules of the SDLT technology, the EIM is
manufactured and tested as a distinct module.
As with all tape technologies, the Super DLTtape II data cartridge is a key
part of the overall system. The main function of the data cartridge is to
provide the magnetic recording media used by the system to store
customer information. The data cartridge also provides the protective
casing that allows safe media movement and storage.
From the outside, the Super DLTtape II data cartridge looks very similar
to the Super DLTtape I and DLTtape VS1 data cartridges. The basic
geometry, write protection switch, and label space are the same. This
simplifies the integration of the SDLT 600A tape drive into existing
operating environments and into automated tape libraries. The
Super DLTtape II data cartridge is easy to recognize; it has a different
color than the Super DLTtape I and DLTtape VS1 data cartridges, and
contains a distinctive pattern molded into the shell. The DLTtape logo
and the product name are also molded into the shell, which ensure you
have a genuine Quantum Super DLTtape II data cartridge.
Quantum A-Series Tape Drives User’s Guide33
Product Specifications
The following subsections contain product specifications for the
SDLT 600A tape drive.
This buckling mechanism engages the tape leaders upon data cartridge
load and disengages them upon data cartridge unload.
Component level tests of buckle arm components have shown at least
250,000 cycles on the tape drive without failure, breakage, or binding; this
includes the take-up leader, the supply leader, and the media itself.

drive Modes
1.The Max-Peak value represents short current spikes drawn for durations of < 50ms. On the 12V supply, the
peaks correspond to the pulse-width-modulated switching of the motors. These values are calculated from the
average of Peak-ripple-current + 2 sigma, measured at nominal DC voltage.
2.The Max-Mean value is the average of the maximum RMS current drawn during this operating mode. These
values are calculated from the average of RMS current + 3 sigma, measured at nominal DC voltage.
3.The typical current is calculated from the average of all RMS current drawn during this operating mode,
measured at nominal DC voltage.
4. The Max DC power is calculated from the typical DC power + 3 sigma, measured at nominal DC voltage. This
value takes into account that the peak currents on the 5V and 12V do not occur at the same time.
5.The Typical DC power is calculated from the average RMS DC power drawn during this operating mode,
measured at nominal DC voltage. This value also takes into account that the peak currents on the 5V and 12V do
not occur at the same time.
6.The Max AC power is calculated from the typical AC power in tabletop tape drives + 3 sigma.
7.The Typical AC power is calculated from the average of AC power drawn in tabletop tape drives.
8.These events last < 1 second and occur at a duty cycle of less than 25%.
9.The Max values for each mode are based on the Max-Mean values, since the peak values are of very short
duration.
(Common Notes)
(1) Voltage tolerance: 5V ±5%, 12V ±5%; Room temperature 24 °C. AC power measured at 117 V, 60 Hz.
(2) DC Current, MaxMean, and DC/AC Power Max refer to the statistically calculated maximum average
requirement based on a sample population of tape drives. These values do not reflect the peak current or power
requirement; this amount is given by the DC MaxPk current.
(3) These results were from the DVT data taken by Percept Technology. Reference the “Power Consumption &
Characterization Test Report” dated 11/28/2005.
(4) Test data set included 12 measurements: 3 measurements of 4 drives.
(5) The 5V “MaxPK” calculated to less than MaxRMS, which does not at first glance make sense. (MaxPK is
calculated at 5.25V, and the switching power supplies need less input current to the same input current.)
Instead, the MaxRMS value was substituted.

SDLT 600A Tape Drive
Recording Method1
The SDLT 600A tape drive uses the Partial Response Maximum
Likelihood (PRML) 32/33 encoding method for reading/writing SDLT
600A tape drive format. It uses the same algorithm for reading SDLT 220,
SDLT 320, and the DLT VS160 tape drive formats.
Environmental Specifications
The SDLT 600A tape drive operates in environments that include general
offices and work spaces with systems capable of maintaining standard
comfort levels.
The following subsections provide the environmental specifications for
the SDLT 600A tape drives (both the internal and the tabletop
configurations). For long-term trouble-free operation, the manufacturer
strongly recommends that SDLT 600A tape drives be used in a clean,
smoke-free environment.
Air Flow Requirements 1
The internal tape drive requires adequate air flow to dissipate the heat
resulting from continuous drive operation. Specifically, the air flow must
be sufficient to keep the tape path temperature below 50 °C.
To allow enough air into the tape drive to keep the tape path below this
temperature, it is important to keep the cooling holes in the rear and the
grill in the front of the tape drive clear of any obstructions that may
hinder the air flow.
Note:It is also important to limit the ambient air temperature to no
greater than 40 °C.

The mean time between failures (MTBF) for the internal drive is specified
at 250,000 hours minimum. This specification includes all power-on and
operational time but excludes maintenance periods. Operational time is
assumed to be 100% of the power-on time. Operational time is the time
the tape is loaded.
LTO Cartridge Specifications
The MTBF for the tabletop drive power supply is 50,000 hours with the
unit operated at full load and 25°C.
Note:The MTBF rating does not represent any particular drive, but
is derived from a large database of test samples. Actual rates
may vary from unit to unit.
Mean Time to Replace1
The mean time to replace (MTTR) is the average time required by a
qualified service technician to diagnose a defective drive and to install a
replacement drive. The MTTR for LTO products is less than 0.5 hour (30
minutes).
The Quantum LTO drives are field-replaceable units. If a problem occurs
with a subassembly or component in the drive, you should replace the
entire unit. Return the drive to the factory in its original packaging.
Contact your distributor, dealer, your computer system company or your
Quantum sales representative to arrange the return.

Data Cartridge Handling Guidelines
Note:The Super DLTtape II data cartridge has a keying feature to
ensure you cannot load it into a previous generation DLT tape
drives.
Data Cartridge Handling Guidelines
By following general handling procedures, conducting careful visual
inspections of data cartridges on a regular, ongoing basis, and being
certain to store data cartridges within their environmental limits, you will
greatly reduce any chance that you will experience problems with your
data cartridges or cause damage to your Super DLTtape system. Respect your media as much as you do your data.
Following these general handling guidelines:
•Always keep each data cartridge in its protective plastic case when it
is not in the tape drive.
•When carrying data cartridges in their cases, always orient the cases
so that the grooves in the cases interlock. This prevents the cases from
slipping apart and falling.
•Never stack the data cartridges in a stack of more than five.
•When placing data cartridges in archival storage, be certain you
stand each data cartridge vertically.
Quantum A-Series Tape Drives User’s Guide54
Data Cartridge Handling Guidelines
•Do not carry data cartridges loosely in a box or any other container.
Allowing data cartridges to jostle together exposes them to
unnecessary physical shock.
•Always observe the proper environmental conditions for storing data
cartridges. Refer to the data cartridge reference card supplied with
each data cartridge. The ambient operating environment for the data
cartridge is
Temperature10
°C to 40 °C (50 °F to 104 °F)
Relative Humidity20% to 80% (non-condensing)
Note: If storage or transportation of a data cartridge has exposed
it to conditions outside the ambient values shown above,
you should condition the data cartridge to its operating
environment for a 24-hour period.
•Maintain clean and smoke-free operating and storage environments.
•Never expose the data cartridge to moisture or direct sunlight.
•Do not place data cartridges on or near devices that may produce
magnetic fields, such as computer monitors, motors, or video
equipment. Such exposure can alter or erase data on the media.
•Avoid unnecessary opening of the data cartridge door; this may
expose the media to contamination or physical damage.
•Do not touch or allow direct contact with the media or tape leader.
Dust or natural skin oils can contaminate the data cartridge and
impact media performance.
•A dropped data cartridge may have dislodged, loosened, or damaged
internal components. If you drop a data cartridge, give it a thorough
visual inspection, as described in Data Cartridge Inspection
Procedure.
•Never apply adhesive labels or “sticky” notes on the top, side, or
bottom of your Super DLTtape II data cartridge. Only use the slide-in
type label provided with each data cartridge and slide it into the label
slot on the data cartridge.
•Do not use graphite pencils, water-soluble felt pens, or other debrisproducing writing instruments on your labels. Never erase a label—
replace it.
Quantum A-Series Tape Drives User’s Guide55
•Be certain you place the unused data cartridge labels in the protective
box so that you do not inadvertently pick them up along with the
data cartridge during subsequent usage. A static electricity charge on
a data cartridge may cause a label to cling to the data cartridge. A
label that is accidentally inserted into the tape drive along with a data
cartridge can prevent the hub reel and drive gear from meshing.
•Follow all data cartridge handling instructions that accompany your
data cartridges or tape drive.
Note:Always remove the data cartridge from the drive prior to
powering down the drive. This ensures that the file system
stored on the tape is consistent and that the tape in the
tape path is not damaged when the unit is powered up.
Data Cartridge Inspection Procedure
Data Cartridge Inspection Procedure
Follow the Visual Mechanical Inspection (VMI) procedures described in
this subsection. These steps will help you identify any potential data
cartridge problems, and will prevent accidental loss of data or damage to
your tape drive.
You should do an inspection if any of these conditions occur:
•As a general practice whenever you change or load a new data
cartridge.
•If a data cartridge is dropped or subjected to some hard physical
shock.
•If the SDLT 600A tape drive becomes inoperable after loading a data
cartridge.
•If you receive a shipment of data cartridges that show any sign of
shipping damage.
Follow these steps to visually inspect a Super DLTtape II data cartridge:
1 Remove the data cartridge from its protective plastic case.

Tape Cartridge Care and
Maintenance2
Observe the following precautions to protect the data on your Ultrium
tape cartridges:
Always:
• Remove the cartridge from the drive when not in use
and store it in its protective case.
• Avoid dropping the cartridge. This can damage
components inside the cartridge, possibly rendering
the tape unusable. If you drop a tape cartridge, open
the cartridge door and make sure that the leader pin
is in the correct position.
• Re-tension a dropped cartridge before using.
• Keep the cartridge away from:
• Direct sunlight and heat sources, such as
radiators, heaters, or warm air ducts.
• Sources of electromagnetic fields, such as
telephones, computer monitors, dictation
equipment, mechanical or printing calculators,
motors, magnetic tools, and bulk erasers.
Do not:
• Expose the cartridge to dirt, dust or moisture.
• Touch the tape media within the cartridge.
• Bulk erase Ultrium tape cartridges. LTO tape
cartridges have prewritten servo patterns that
cannot be reformatted by the tape drive. A bulk
erase operation would make them unusable.
• Use tape cartridges outside the specified operating
conditions: 10
o
C to 40o C, 20% to 80% relative
humidity.
If a tape cartridge has been exposed to conditions
outside the specified range, recondition the tape
before using in the operating environment by
exposing it to the operating environment for a time
equal to or greater than the time it was outside the
operating environment, up to a maximum of 24
hours. Then re-tension the tape to stabilize the tape
pack for better performance.

Data Compression
A process that reduces the amount of storage space
required to hold a particular block of data. Data transfer speed
and total media capacity are affected by the data compression
achieved. In accordance with industry practice, a typical
compression ratio is 2:1 of data storage. Actual compression
ratios achieved depend on the redundancy of data files being
written.
