Archival Gold - built with these layers
- Phthalocyanine dye is fast reacting, long lasting, saves data much longer, lasting a lifetime with normal use.
- 24k Gold layer reflective coating, (instead of silver), protects a disc with a scratch-armor layer, other discs omit.
- Lacquer layer over the gold prevents peeling and plastic rot – a common problem among ordinary store-discs.
- Diamond protective layer applied to the lacquer to prevent scratching with normal use, not found in store discs.
- Green dye is its only protective Layer
- Not resistant to peel, crack, chip, oils;
- Not resistant to fingerprints, scratches,
- These discs will not last 5 to 7 years;
Diameter: 120 mm
Thickness: 1.2 mm

- USB-Drives Need Charging Every 4 Weeks
- Hitachi Glass Disc was a Rumor from 2012
Archival Gold is Lab Tested for Aging and Endurance with Extreme HIgh and Low Temperatures
- Recording condition temperature -15 - 35 C, Humidity 45 - 75 %RH lower than normal
- Playback condition temperature -5 - 55 C, Humidity 5 - 95 %RH lower than normal
- Transportation condition temps -20 – 60 C, Humidity 5 - 95 %RH, test period 2 weeks
- Storage condition temperature 5 - 30 C, Humidity 8 - 60 %RH, aging test 300 years
Estimates of Aging Endurance is Based on Effects of Temperature, Relative to 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.
5 Stress Conditions are Defined During Disc Testing to Meet Delivery Requirements
Test Cell numbers are Stress Tests in an Incubation period in a minimum total time and minimum equilibration duration.
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
Before and after, each incubation period is tested for error rates for Max-BLER for CD's and Max-PIE8 for DVD-R.
Failure is defined by error rates that exceed Orange Book standards defined by Sony/Philips, DVD-R specifications
defined by the DVD Forum. Due to the length of a test, results from Test Cell number #1 is used: 80C / 85% RH.
Life expectancy is estimated according to ANSI guidelines based on the use of the Eyring models which is a
mathematical equation derived from thermodynamic laws.
The following is the conclusion for the 5 test periods, as the first Test Cell is being used
Tested at eFilm - these estimates are based on results from industry standard tests subjecting discs to 85%
relative humidity and 110 degrees Celsius for 2000 hours. The Light Fastness Test shows that eFilm tested
Archival Gold to 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.
Archival Gold is produced with Phthalocyanine dye under strict manufacturing conditions which insure that data is
safely preserved per each Archival Gold disc as tested to last from 100 years to 300 years under normal conditions.
