All about CDs
The MAM-A Difference
MAM-A Inc. has developed a reputation for quality that is un-equaled in the CD industry.
Because of their patented
Phthalocyanine (thalo-sy-a-neen)
dye and their attention to detail in the manufacturing process, MAM offers recordable
media that is more reliable and longer lived than any other recording media available
today. If you store it on MAM-A CD-R, you can be sure that you can reliably retrieve
it for a long time to come. In fact, MAM conservatively estimate that 'MAM-A Gold
CD-R' will last in excess of 300 years when stored at room temperature. No
other recording media that we know of can offer that kind of reliability (tapes
don't come close and even "stamped" CDs will last 5-25 years at best).
The MAM-A Advantage
MAM-A CD-R media benefits from a consistency and process control which no other
manufacturer can equal. Since MAM don't rely on third-parties to provide our technology,
production facilities, or raw materials, MAM-A CD-R customers know that each component
and each step in the manufacturing process has been subjected to the most rigorous
quality controls in the industry. Every MAM-A CD-R is
warranted
for life. No other CD-R media manufacturer offers a warranty of this strength.
Every MAM-A CD-R is certified for use with all high speed recorders up to 52X. There
are two reasons for this. Firstly, MAM-A's molding process results in discs that
are flatter than the competition. While all discs are slightly warped, if they are
warped beyond a certain tolerance they cannot be used for high speed recording.
Secondly, the unique characteristics of the Phthalocyanine dye simply works better
in high speed writers than other dyes. Some of the key parameters to judge CD quality
actually improve at higher speeds with MAM CD-R.
High Speed Compatibility
Phthalocyanine dye is more sensitive to powered
laser light and more conducive to high speed recording than other dyes. It is altered
more quickly and sharply by the laser. Therefore it guarantees very precise recording
at speeds 2X-52X with any type of recorder, and errorless read back by any type
of player. Since MAM have not changed their dye formulation in over 5 years, drive
manufacturers are able to easily configure their units for the dye. That's why MAM
CD-R is compatible with every writer & reader on the market. A CD-R that
we manufactured 5 years ago will perform the same as the ones made today. Most of
our competitors need to re-formulate for different speeds, requiring drive manufacturers
to accommodate multiple variations.

by other manufacturers.
CD-R Dyes: How to Tell What's What
You’ve seen the references to "gold dye", "green dye", "blue dye", "silver
on gold", "silver on silver" as descriptions of CD-R media. It gets rather confusing
when trying to understand which is which, even with samples right in front of you.
This way of describing CD-R media originated innocently enough when the industry
was younger and gold CD-R media was the only type available. At that time, you could
pick up a CD-R, turn it over, and see either a green color or gold color…simple
enough. Much of the confusion started when silver CD-Rs were introduced, changing
the apparent color of the dye. Cyanine (blue) dye appears green on gold media and
blue on silver media.
Phthalocyanine appears transparent on gold media,
but light green on silver media. The term "Gold on Gold" is used because the disc
looks gold on both sides.
There are three types of dye currently in use for CD-R media:
*Mitsui Chemicals Inc. holds a worldwide patent on phthalocyanine dye.
**Not in widespread use

Gold DVD+/-R
In order to meet consumer demands for high capacity, long life data storage, MAM-A
Inc. has developed a Gold Archive Grade, recordable DVD media. The media is capable
of storing any type of data or video content and is available in -R and +R formats
for 4.7 GB of total storage space. This product uses 24 karat gold as the reflective
layer, offering maximum resistance to chemical breakdown -- one of the major causes
of disc failure. The MAM-A Gold Archive Grade DVD is offered as the long awaited
companion to the MAM Archive Grade Gold CD-R which has earned a reputation for the
best longevity of any storage media.
Superior Dye Formulation
Unlike other DVD-R manufacturers, MAM-A has developed a brand new organic dye formulation
used in the production of every MAM-A DVD-Recordable disc.
Superior Longevity
MAM-A Gold DVD-R discs have a life expectancy rating in excess of 100 years - ideal
for archival use.
Global Compatability
Once written to, a MAM-A DVD-R disc adapts the same playback characteristics as
a DVD-ROM disc, rendering it compatible with the world-wide base of both DVD video
players and DVD-ROM drives which support DVD Recordable media.
Superior Physical Strength
DVD-Recordable discs are manufactured by bonding two 0.6 mm “halves”
together to make one 1.2mm DVD-R; each half, capable of containing its own recording,
reflective and protective layers. The adhesive
structure
of MAM-A DVD-R is unique to our discs and has proven to have a higher bonding strength
than other discs. Physical tests to this bonding layer resulted in flawless
results of the MAM-A DVD-Rs, which experience no signs of peeling or damage to the
bonding layer.

DVD Sides and Layers
Single-Side, Single Layer Disc is the most basic Configuration for DVD. It
had a maximum storage capacity of 4.7GB. This 4.7GB is 7 times the capacity
of CD.
Double-Side, Single Layer provides a total of 9.4 GB. Half of the data is on the
second side. It requires flipping the disc.
