Disc Quality

The high demand and dramatic increase in CD media,
plus the competitive pressures to squeeze out
every possible cost and improve the profit margins
have given rise to many manufacturers of CD related
media.  To help reduce the costs of increasing
capacity, many of these firms have relocated their
old manufacturing lines and hired staff that learn
on the job.

The biggest problems with CDs occurs when discs are
produced using older equipment then end up failing
when you try to use them.  Luckily, most of these
types will fail when you first try to record on
them.  There is however, a likelihood that the disc
will complete a burn and the media won't play at
all.

The agony of taking your photo or video treasures
and putting them on CD or DVD and then deleting them
from your camera or computer only to realize that
the copy is corrupted is far too much to risk.  The
brand name company's such as Verbatim choose to
guard their reputation for quality and durability
by using only advanced recording dye and other
types of technology to produce high speed discs.

The stability of the recording dye is very critical
as heat, humidity, oxygen, and even UV light can
degrade the dye.  Verbatim research has also proven
there is a strong correlation between the production
and bonding processes of disc quality.

For data and personal pictures that are important,
you should always buy quality CD media.  Then,
before you go ahead and delete the source file,
trying playing the disc back to ensure that it
copied correctly.  This way, you won't have to
worry about losing your precious files and photos
when you remove the source from your computer.

Quality At A Cheap Price

There has never been a better time than now to have
your audio book, music project, computer data, or
CD-R business card duplicated.  Unlike the days gone
by, these processes are cheaper than ever before -
even for those on a budget.

Over the last several years, the costs of blank CDs
have dropped quite a bit.  The retail chains such
as Office Max, Staples, and Best Buy run specials
on blank CDs where you can purchase a 50 CD-R spindle
for under $20.  You can even find similar deals
on Froogle, such as a 50 pack spindle of blank CD-R
disks for less than $12.

Those interested in CD duplication at home, will find
that many of the newer computers come packages with
a CD burner included at prices under $500.  If you
already own a computer and want to add an internal
CD burner, several retailers have brands for under
$50.  You can also purchase an external CD burner
for all your needs for under $100.

Making cheap duplications of CDs even more affordable
are the powerhouses such as DiscMakers, Oasis,
and CDman, all of whom specialize in duplicating
large quantities of CDs at low prices.  Not only
do these powerhouses offer superior quality at
a great price, but they also give great deals
on graphics, CD inserts, and jewel cases as well.

With cheap prices, you can get everything you need
at a price you can't argue with.  If you've
copied CDs in the past, you can quit paying high
costs and save yourself a ton of money.  Those
who offer CD duplication at a cheap price are
great at what they do - saving you a ton of money
for your CD duplication needs.

CD Mastering

Even though many assume that the mixing of the
seperate audio tracks is the final step, a recording
should always be mastered well in order to sound
great.  CD mastering is the final chance for
creative input when you create a compact disc.
After the discs has been mastered, it can be printed,
reproduced, and then sold.

The process of mastering a CD actually involves
several steps.  The first step is putting the songs,
or tracks at this point in the correct order.  The
length of time between the songs is also adjusted,
along with the editing of the songs.  Any unlisted
or secret songs on the CD are normally added at
this point as well.

There are several ways that you can go about
mastering a CD.  First of all, the mix can be
sent to a professional CD mastering engineer,
which is what professional musicians normally
decide to do.

The mastering engineers will often work in their
own mastering facilities, which are very different
from standard studios, in the fact that they have
much less gear and are designed for the best
possible playback of the mix as possible in
order to fix anything that's wrong. 

Aside from mastering engineers, CDs can also be
mastered at home using computer software.  This
option is normally more realistic for unsigned
artists or musicians who are just starting out
with their music.  Depending on the software
quality and skill of the individual doing the
mastering, the CD may turn out perfect or it
may sound very unprofessional.

You can also refer to online CD mastering as
another option.  Cds that are mastered online
can be great, as instead of sending a mix to a
mastering engineer, the mix is instead sent
via the Internet.  To do this, you'll need a
high speed Internet connection.

The cheapest way to go about mastering a CD is
with free mastering.  Artists and musicians may
choose to use free mastering programs with
demos or other earlier recordings that artists
will use to send to major record labels to
generate some interest in their music.

The major differences with a professional CD
and an amateur recording is normally found in
the mastering.  Every song that you hear played
on the radio is thoroughly mastered in order
to sound better.

While you can master using free programs or
your computer, a professional CD mastering
engineer is normally the best way to do business
if your band is looking to make a profit from
your music.

CD Terminology

Below, you'll find the most common terminology that
relates to CD duplication.  Even if you are new to
duplication, the terms below may help you learn more.

BLER
Block Error Rate.  This is the raw digital error rate
before any type of error correction.

CD
This the Compact Disc, a digital medium that's formed
of a 12cm polycarbonate substrate, a reflective
metalized layer, and a protective lacquer coating.

CD-R
Compact Disc-Recordable.  The term CD-R is used to
describe the technology of recordable CD along with
the equipment, software, and media that are used to
make the recordable disks.

Data layer
With CD-R media, this is the organic dye that is
sandwiched between the polycarbonate substrate and
the metalized reflective layer of the media.  CD-R
disks don't have any data on them at all until the
are recorded.

Injection Molding
This is a manufacturing method where the molten
material is forced into a mold, normally under
high pressure, then cooled so that the material
will take on the shape of a mirror image in the
mold.

Media or blanks
CD-R media are the disks that are used to record
digital information using a special recorder and
premastering software with a computer.  These discs
are made of a polycarbonate substrate, a layer of
organic dye, a metalized reflective layer, and a
coating of lacquer for protection.

Organic dye
The data layer of CD-R media is made from a dye
that is melted during the process of recording.
Where the dye is melted, becomes opaque or
refractive, scattering the reading laser so that
it isn't reflected back into the reading sensors.

Reflective layer
This is the  metal later that sits on top of the
dye that reflects the laser beam back to the
reading assembly.  This is normally 24k gold in
CD-R disks, although it can be silver as well.

CD Ripper

CD ripper software will open up an entirely new
way of how you listen to music.  With the use of
CD ripping software, you can take audio tracks
from a CD and them into audio files for use on
your computer.  You can save them as WAV, MP3, OGG,
or WMA audio files.  The term "ripping" is the
term used to describe this very process.

There are advanced CD ripper software as well,
which allows you to convert back and forth between
these formats.  You can also get software that
can record vinyl LPs and cassettes to create those
same audio files for your computer.

You can get a variety of ripper software programs
online by searching the internet.  Most software
is user friendly and offers you a variety of
options.  You should however, do some searching
and comparing before you decide which CD ripper
program is best for your needs.

Each type of CD ripper software will offer it's
own style and interface.  You should always make
sure the CD ripper software you choose is easy
to use and easy to understand.  It doesn't matter
how good the software is - if you can't use it.

When you explore the options of CD ripper software,
make sure you also check the software's editing
abilities.  With most programs, you can select
the output format for the music.  This will
include the bitrate, channels, and even the
frequency. 

Quality ripper programs will also tag the
encoded audio files with medadata, which will
contain information about the artist, song title,
track number, and even the album title.  This
will automatically be input for the file. 

Another great feature with some ripper programs
is the ability to delete the silence at the
beginning or end of song tracks.  Some programs
will even give you the ability to edit the
songs themselves, giving you full control of
the sound provided by your files.

For those who enjoy to listen to their music
from a CD, a CD ripper can aso be used to
select your favorite songs and create a mixed
CD.  Some rippers will even let you rip audio
tracks directly from a CD then burn them to a
new CD - without having to save them as a new
audio file.

With millions of people ripping CDs these days,
CD ripping is the wave of the future.  You no
longer have to keep your music on your computer,
as you can rip them to a CD or even put them
in your favorite MP3 player and take the music
with you - wherever you go.
