Digital Agenda: "Comité des Sages" calls for a "New Renaissance" by bringing Europe's cultural heritage online
On that occasion we have, by convention, Dr. Elisabeth Niggemann (Director General of the German National Library and chair of the Foundation for the European Digital Library) always informed in due time prior to these meetings on the current state of our technology for long-term preservation as the only one with unlimited shelf life. The novelty lies in our announcements in the emerging highly automated manufacturing capacity, which makes this originally very expensive technology for all archives, libraries and computer centers and even for private users affordable and can thus be used even for radical (up to 75%) cost reduction. The technology itself was not unknown, since the report of the Académie des Sciences and Académie des Technologies (see below) since the 29.03.2010 is known and has been prepared with recommendations for effective policies of the digital archiving on behalf of the French Government and the EU. We have also submitted the necessary information about the SDG-Masterglass technology local bar Members of EU Commission Vice-President Ms Neelie Kroes and Culture Commissioner Ms Andoulla Vassiliou and the Directorate-general for information society and medias provided. During our conversation Ms Elisabeth Niggemann has made it unmistakably clear that she considers any dependency on firms or a technology for unacceptable and wants to avoid. We consider them for very important, because: Our etched glass discs after the one production absolutely no longer necessary to contact the manufacturer. We call it long term archiving. The previously known digital storage technologies, but do not allow long-term archiving,only sequential backup. The constraint of short life cycles of magnetic media for regular exchange (tapes in every 2-3 years, drives about every 5 years) would mean financial and technical dependence. A unique absence of such change of generations would have catastrophic consequences. To suspend the European cultural heritage such a Russian Roulett would be ignoble and irresponsible. Accordingly, the default recommendations like OAIS, nestor, etc.are still based on sequential backup finally to be upgraded to real long-term archiving. A lot of unnecessary activities and costs can be eliminated so easily.
The Royal Way of archivingThe Japan Aerospace Exploration Agency, JAXA, sent on the 21th May 2010 the spacecraft IKAROS into space. This probe will use solar-photon sail. On board he has is an etched glass DVD, which Planetary Society once again with a "Messages from representing the Earth." Just as in 2007 with the NASA Phoenix Mars expedition (see below).
This time, however, the glass DVD out there in free space, that is, in minus 270 degrees Celsius and all cosmic and solar radiations exposed and vulnerable. The disc was produced by our technology director Pascal André. This serves as a new reference for our unlimited durable SDG-Master Glass archiving technologies.
Longevity of Digital InformationThe data that we want to keep will disappear?  Our societies generate ever larger masses of information, while the lifetime of digital media available to keep has never been short. If this problem is properly taken into account in a few specialized agencies, it is widely ignored by the general public and the majority of institutions or companies. Thus a large amount of personal information, medical, scientific, technical, administrative, artistic, etc. is in real danger of extinction.
Faced with this alarming situation, the Academy of Sciences and Academy of Technology have formed an expert group which publishes its recommendations in a report presented a preview:
Longevity of Digital Information In the presence of Jean Salençon, President of the Académie des Sciences and with the intervention of the authors:
Download The report of the joint working group of the two academies now officially confirmed, that only our glass discs are reliable media, which are really suitable for long term archiving. The report states, that this disc is "using a lithography process which makes it very stable over time: it passes with flying colours all aging tests. To avoid community "astronomical cost" a "major power" were included, they recommend the development of one "real digital archiving policy" research to develop and "Promote innovation". They insist, "strong support" the few companies that "Progress" in establishing recordable media "very good durability made have."
Long-term archiving on the glass discs etched with rectangular pits with no reflective layer. The potential for radical cost savings by up to 75%. Guarantees:
With the directly into the tempered glass discs etched pits, it became possible to produce the pits for the sampling optimal rectangular shape. Thus the benefits of technology come with sharp edges and high slope even better coverage. The laser light reaches the photo diode steeper slopes in the output signal. The pit structure achieved with this technology is so clean that the player can read them without a reflective layer. Only the intensity of the laser needs to be readjusted, what most players are able to do for themselves. This is especially important for long-term archiving, which can be dispensed by the reflective layer and the protective lacquer. So we can just use the glass discs. Of course, the gold-coated "traditional version" is still to choose from.
This product is the first and only media in the world, which holds up forever, "as carved into the stone." All magnetic data storage systems such as hard disks and magnetic tapes can be compared to our solution only for temporary use will be considered suitable. Most only as a backup but not as long-term archiving. For large data centres and archives are robot-controlled jukebox systems used up to 5000 discs per cabinet. This allows that step by step great tape and disk resources to be replaced. The days of continuous data copy, refresh, re-emerging among the ever-data loss are a thing of the past.
Readability without drives
Gone are the days when you just had to copy everything over again, where a fire, water or electricity damage could destroy valuable documents. Our glass discs must be done only once and accessibility, network or broadcast capability and forgery are secured forever. A medium is the passive, requires no maintenance, no electricity, or cooling, resists heat, cold, acid or even magnetic fields and its keeping is completely without costs.

Common question, what if it in 100-500 years no longer have optical drives? Now this image shows how a HD disc with high-resolution scanner to be read without rotation. This property is unique, no other digital media can imitate.
