Re: CD Lifespan?

2006-01-16 Thread Atherton, Tim








I attended a very good workshop on
longevity and storage of optical and magnetic media put on by the Canadian
Conservation Institute three or four years ago.

At that time they were in the middle of
some very detailed research on the longevity and reliability of CDs and
DVDs

I saw a lot of their raw data and tentative
conclusions at the time, but I believe much of the work was since published by
them, though Ive never actually followed up on tracking down the papers

Even with magnetic tape, you will face carrier degradation and 
potential loss of information over time. This topic appears 
again and again on the Association of Recorded Sound Collections 
(ARSC) listserv  and has been addressed by the International 
Association of Sound Archives technical committee. 

There is certainly a lot of uncertainty about CD longevity. Much 
of which has to do with recurrent changes in the chemical make-
up of CDs as the industry responds to public demand, cost 
concerns, etc. 

For more information see:

The August 2005 issue of RLG DigiNews (an online journal) 
contains an article titled FAQ: Predicting the Life Expectancy 
of Modern Tape and Optical Media by Vivek Navale of NARA. The 
article provides in-depth summaries of several stu! dies by LOC, 
NIST, NARA, and
others.

Another interesting article on lifespan and brand-based testing of CD-R
media is

The study is somewhat incomplete in that it doesn't cite the specific
type of cd's manufacturers, only the retail brand names.





Otherwise, it is a really interesting study.

2006-01-13 Thread Perian Sully



Speaking of storage, has anyone here had good luck using 
Iomega's Rev drives? They're relatively new as far as I know, so maybe there 
hasn't been enough time to test degradation, but they hold a lot of information 
and they're compact and cheap.

  Here's 
  something that will certainly raise some eyebrows. We'vedebated this 
  topic on the list beforeI just read a recent PCWorld article on-line 
  entitled, "Do Burned CDsHave a Short Life Span?", in which a storage 
  expert at IBMDeutschlandestimated that the average CD has a 2-year 
  lifespan. Better CDsshouldlast maybe twice that long. He 
  recommends magnetic tape for long-termstorage. The brief 
  article can be accessed at:http://msn.pcworld.com/news/article/0,aid,124312,00.asp?GT1=7645
