Re: CD Lifespan?
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 Tim Atherton Timothy Atherton Information Management Technician Museums and Collections Services Ring House #1 University of Alberta Edmonton, Alberta Canada T6G 2E1 From: Mike Rippy [mailto:mri...@ima-art.org] Sent: Monday, January 16, 2006 6:48 AM To: mcn-l@mcn.edu Subject: Fwd: CD Lifespan? from h-oralh...@h-net.msu.edu malar...@unr.edu 1/14/2006 4:01:52 PM From: McCormick, Kathleen kmcco...@email.uncc.edu Subject: CD Lifespan? Date: Fri, 13 Jan 2006 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. http://www.rlg.org/en/page.php?Page_ID=20744 Katie McCormick Reference Archivist and Coordinator for the Oral History Program Special Collections - J.

Re: CD Lifespan?
This link also contains useful information ...the US National Archives and Records Administration requested that the National Institute of Standards and Technology generate data that could be used to develop authoritative care and handling instructions for optical media.

Re: CD Lifespan?
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. Perian SullyCollection Database and Records AdministratorJudah L. Magnes Museum - Original Message - 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.
