See “Do gold CD-R discs have better longevity than green discs?
http://www.mscience.com/faq53.html. http://www.cdpage.com/dstuff/BobDana296.html has a very readable description of CD-R media error testing that leaves you with a numb sense of amazement that CD-Rs work at all. It also explains the errors that come out of MSCDEX and what the dreaded E32 error means to a CD stamper. Highly recommended.
http://www.mscience.com/faq53.html. There’s a very readable discussion of CD-R media error testing on http://web.archive.org/web/20031211151723/http://www.cdpage.com/dstuff/BobDana296.html that leaves you with a numb sense of amazement that CD-Rs work at all. It also explains the errors that come out of MSCDEX and what the dreaded E32 error means to a CD stamper. An interesting document entitled “Care and Handling of CDs and DVDs – A Guide for Librarians and Archivists” can be found on the web sites for the National Institute of Standards and Technology (NIST) and the Council on Library and Information Resources (CLIR). View it on the web at http://www.clir.org/pubs/reports/pub121/contents.html or as a PDF from http://www.itl.nist.gov/div895/carefordisc/CDandDVDCareandHandlingGuide.pdf. It has a wealth of information about disc composition and longevity, as well as recommendations for extending the lifespan of your media. Another good NIST article, “Stability Comparison of Recordable O

See http://www.kodak.com/global/en/service/cdrMedia/index.jhtml, specifically the “KODAK Ultima Lifetime Discussion” and “KODAK Ultima Lifetime Calculation” white papers (currently in PDF format). The last page discusses the Arrhenius equation, which is used in chemistry to calculate the effect of temperature on reaction rates. The Kodak page defines it as: t = A * exp(E/kT) where ‘exp()’ indicates exponentiation. ‘t’ is disc lifetime, ‘A’ is a time constant, ‘E’ is activation energy, ‘k’ is Boltzmann’s constant, and ‘T’ is absolute temperature. The equation allows lifetime determined at
