Archival Gold Longevity Test White-Paper:
Tests were conducted according to ANSI/PIMA IT9.27-1999 guidelines entitled:
" Life Expectancy of Information Stored in Recordable Compact Disc Systems --
Method for Estimating, 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" (shown below). A stress condition is defined by, for example: 2000 hours (in
500 hour segments) at 85% relative humidity and 80 centigrade temperature. 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 (CD) due to rapid transition of temperature.
Archival Gold CD Manufacturing Stress-Test Engineering White-Paper:
5 Stress Conditions are Defined:
Before beginning the test and after each incubation period the discs are tested for error rates for 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). Due to the length of the test, results from only Test Cell number 1
are sometimes used: 80C / 85% RH. Life expectancy is estimated according to ANSI guidelines based on the use of the
Eyring model which is a mathematical equation derived from thermodynamic laws. The following is our test
conclusion for 5 test periods. The first Test Cell Number is used here.
Test Cell number Test Stress Number of samples Incubation period (hours) Minimum Total Time (hours) Min
Equilibration duration (hours): Equilibration is the time spent at ambient humidity before removal from chamber.
Test Cell# Test Stress # of Samples Incubation hours Minimum Total Hours Min. Equilibration hrs.
1. 80C, 85% RH 10 500 2000 6
2. 80C, 70% RH 10 500 2000 5
3. 80C, 55% RH 10 500 2000 4
4. 70C, 85% RH 15 750 3000 8
5. 60C, 85% RH 30 1000 4000 11
Environmental tests show that the eFilm Archival Gold CD-R will last up to 300 years (under proper storage conditions).
These estimates are based on results from industry standard tests that subject the discs to 85% relative humidity and
80 degrees Celsius for 2000 hours. The Light Fastness Test shows that eFilm Archival Gold will withstand the full
spectrum of light, same as the sun, for 100 continuous hours without damage. Our competitors' discs, with cyanine
dye, begin to deteriorate after only 20 hours and fail at 65 hours. All of our CD-R media is produced with the patented
Phthalocyanine dye under strict manufacturing conditions to insure that your data is safely preserved for years.

Archival Gold Disc Specs:
- Diameter: 120 mm.
- Thickness: 1.2 mm.
- Hole diameter: 15 mm
Comparisons: Store-Bought CD vs Archival Gold CD:
- Only last 3-7 Years. Files will disappear without explanation.
- Can be destroyed by ultraviolet light, heat, humidity, water.
- No gold layering and no lacquer scratch protection layers.
- Basic plastic magnetic, same principals as 1950's records.
- Temporary storage meant for mobile peer to peer data filing.
- Lesser strength, not meant for long storage or music play.
- Basic silver surface finish does not resist fingernail scratch.
- Gold scratch-armor layer, tested for longevity (below);
- layers protect the disc 10 times better than store bought discs;
- Protects against scratches, scuffs, dirt, chemicals, fingerprints;
- Lab-accelerated tests for aging process to prove its Longevity (see below)
- Phthalocyanine dye - long lasting for data longevity - not on store-bought CD.
- Gold reflective finishing layer, instead of silver finish found on store-bought CD.
- Has a lacquer layer over the gold to prevent peel, a common problem on CD's.
- Has a diamond protective layer over its lacquer which prevents any scratches.
