That makes the case for gold - no doubt - so I did a news.google.com search of Phthalocyanine and came up with this recent article: blogcritics.org The change in light intensity changes every time the laser goes over a pit into the land area and vise-versa. The reflective material is made up of either silver, gold/silver alloy or pure gold. Gold/silver alloy is recommended for the most cost efficient and stable choice but if you have deeper pockets always choose pure gold archival CDs whenever possible to achieve the maximum archival ability. According to Kodak, tests have shown Kodak CD-R Gold Ultima, which uses a pure gold reflective layer, to have a life expectancy of 200 years. Other Kodak media using gold and silver alloys have demonstrated archival capabilities of 100+ years. This not a product endorsement because it's just an example and information based on the best possible life expectancy for these disks. You can take that for what its worth. The most important thing to come away with knowing is that gold disks, although they will cost you much more, have shown greater permanence in many tests and are the highly recommended solution for users such as ourselves that are interested in maximum archival time. Silver corrodes through reaction with sulfur dioxide, an environmental pollutant that can migrate through the disc with moisture causing the disc to reduce the reflection of the laser and resulting in the data becoming unreadable. Therefore, silver is a good solution but for longer term storage, it's not the best choice for obvious reasons. Gold is obviously the best choice but is traditionally more expensive. For our purpose here I would recommend buying nothing but discs manufactured with gold reflective layers and ensuring that you have taken that extra step to preserve your data. You won't even miss that extra $1.00 five years from now when those discs read like a charm. Now if gold is a 10 bagger like puplava claims - those disks will go up 10 times in price no? Will you still want a 300 year storage medium at 10 times the price when maybe a substitute that is only 100 years will be 10X cheaper? I had some friends at IBM from Ga Tech who wanted to look beyond what was now and see into their crystal ball future gtresearchnews.gatech.edu They told me this 10 years ago though - and it doesn't seem like much progress has been made from 2d single layer storage to 3d multi layer storage. I don't want CD/DVD archives of all the stuff I read, hear, or see, I want it archived centrally in the matrix and as me and 12 billion other people want to use it we download it into local temporary storage until we are satiated. I don't want a cd/gold dvd copy of SI - I want it archived on the servers it is at now and be able to access it from anywhere on the planet through my wireless web. Do you want to send 1000 people your wedding photos on a gold DVD or would you rather upload it to one central archive and then let them access it at thier hearts content? Should Jay chen buy a lot of gold DVD/CD's for little coconut to archive her photos or is putting them on the web for all of us to see the best way to disstribute his pictures? I used to have a lot of CD's - then all my geek friends converted to MP3 - I converted some too - but I found turning on musicmatch and listening at the ethnic fusion channel for free matched a lot of my current cd's. I turned on yahoo messenger with their launchcast dance station also matched a lot of my cd's - so i just saw no point in converting to mp3 when the matrix was going to stream all the music I like for free. I have three stooges on DVD because I don't know anywhere I can go on the net for free and click a button and the stooges in all thier glory start streaming into my monitors - but if that day comes, I won't keep the DVD around either I don't think. Why should I archive it if some matrix entity is going too and let me watch it anytime I click the button? From an investment perspective you really think I should buy gold coins because gold is in 300 year cd's? Is the future a blockbuster model where 12 billion go to their store and check out a DVD with gold in the reflective layer or is the future where 12 billion click a button and the matrix sends the latest daily show with jon stewart into their monitors over a net connection?
