Re: CD Lifespan?

[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 CD’s and DVD’s 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 I’ve 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.
