« Both recordable CDs and DVDs can be very stable and robust, » the working group says on its Web site.
« But, as occurs with many successful technologies,
a multitude of suppliers have entered the worldwide marketplace with varying degrees of product quality. »
En raison du vieillisement irréversible des supports inscriptibles, le renouvellement des sauvegardes de fichiers doit s'effectuer dans les cinq années consécutives à la gravure d'origine
Je veux bien, mais cette période de 5 ans est elle uniformément valabledans les cinq années consécutives à la gravure d'origine
J'espère que dans l'article il ne vont pas juqu'à faire une subtile disntinction entre données (data) et vidéole renouvellement des sauvegardes de fichiers
Mais la question est:
Comment allons nous déterminer d'une manière précise
si les données d'un CD-R ou DVD R gravé
se trouvent en péril ?
pour ensuite essayer de les récupérer tant qu'il en est encore temps !

In a recent issue of Computerworld Magazine, John Blau reported, "Unlike pressed original CDs, burned CDs have a relatively short life span of between two to five years, depending on the quality of the CD."
The silver reflective layer eventually tarnishes through exposure to light, heat, oxygen, humidity and rough handling. For some, this may mean the loss of key data or precious memories such as wedding and family photos.
The 24-karat gold reflective layer on the KODAK Preservation CD-R and Preservation DVD (-R) will not tarnish or oxidize. Phthalocyanine dye, an extremely stable medium for long life, is the primary data storage layer in the CD-R.
In addition, triple layers of protection guard against heat, humidity, bright light and the effects of rough handling.
The substrate of the CD-R is optical grade polycarbonate, better than many CDs on the market.

se conserveront-ils vraiment mieux que les autres ?

Une chose est déjà sûre: ils seront plus chers ...
[buck] a écrit:I guess Memorex is using B Grade media for their Gold media, just like their regular media.
RJW a écrit:Hmm I'm not suprised. Fact is that any TTH01 disc I have seen not sold under the TDK brand hasn't performed nice.
So this is just a long those results.
