Mitsui
Gold Archival DVD-R and DVD+R
Mitsui gold DVDs are widely considered to be the
most stable DVDs available. They are the choice of archivists and others
requiring long-term preservation of digital data. Made in the Finally a
DVD suitable for storing your most precious files! The MAM Gold Archive
Grade™ DVD is designed for applications requiring long-term storage of sensitive
data, video or music files. The reflective layer is comprised of 24 karat
gold, which allows maximum resistance to chemical breakdown -- one of the
major causes of disc failure. Along with choosing the right recording dye
material and bonding agent (Note: A DVD is made of two polycarbonate discs
bonded together) the long-term stability of the reflective layer is crucial.
Reflective layers using your standard “silver” surface are subject to
oxidation (rust) over a long period of exposure to moisture. Unlike silver
jewelry, a gold ring won't rust and neither will the gold reflective layer in
this disc. In optical discs, the use of gold can triple the life of a
standard disc. Preliminary tests show that the MAM Gold Archive Grade™ DVD
can last significantly longer than ordinary silver recordable DVD discs. MAM Archive Grade Gold DVD
Longevity The MAM Gold Archive Grade™
DVD is designed for applications requiring long-term storage of
sensitive data, video or music files. The product uses 24 karat gold as
the reflective layer, offering maximum resistance to chemical breakdown --
one of the major causes of disc failure. Preliminary tests show that
the MAM Gold Archive Grade™ DVD lasts significantly longer than ordinary silver
recordable DVD discs. The chart below shows 2
silver DVDs that have failed in less than 500 hours and another silver DVD
that did much better, but the MAM gold DVD still has error rates well
below the upper limit of 280. At this pace, we are expecting a lifetime
of over 100 years. The MAM Archive Grade™ Gold
DVD is offered as the long awaited companion to the MAM Archive Grade™ Gold
CD-R which has an expected lifetime of 300 years and has earned a reputation
as the highest quality storage media available today.

MAM longevity tests are conducted according
to ISO 18927-2002 guidelines titled: "Imaging
materials -- Recordable compact disc systems-- Method for estimating the life
expectancy based on effects of temperature and relative humidity" In general, the test consists of placing samples in an
environmental chamber at specified temperature and humidity levels for 5
different "stress conditions". A stress condition is defined by, for example, 2000 hours
(in 500 hour segments) at 85% relative humidity and 80 centigrade.
Temperature and humidity "Incubation" periods are reached gradually
with the use of ramp times. (This is done to avoid a shock condition
where bubbles can form in the media due to rapid transition). The 5 stress conditions are defined as
follows:
(Equilibration is the
time spent at ambient humidity before removal from chamber) Before
beginning the test and after each incubation period the discs are tested for
error rates. Max BLER for CD-R and Max PIE8 for DVD-R. Failure is
defined by error rates that exceed Orange Book standards (defined by
Sony/Philips) or DVD-R specifications (defined by the DVD Forum).
Life expectancy is
estimated according to ISO guidelines based on the use of the Eyring model
which is a mathematical equation derived from thermodynamic laws.
