Predicting Life Expectancies of Modern Magnetic and Optical Media
December 21, 2005, 10:30 to 11:30 a.m.
West Dining Room, 6th floor James Madison Building
ABOUT THE LECTURE:
This presentation will describe the findings of recent studies conducted
by the U.S. National Archives and Records Administration, the Library
of Congress, and the National Institute of Standards and Technology to
address
stability and life expectancies of higher density magnetic tapes and
optical discs. The effect of environmental factors on physical and chemical
composition of magnetic tapes and optical media will be highlighted.
Accelerated aging studies, chemical and error rate dependent models,
and statistical approaches for analyzing the experimental data will be
discussed.
ABOUT THE SPEAKER:
Dr. Vivek Navale has been the Technical Chief for the Electronic Records and Special Media program at the US National Archives and Records Administration (NARA) since 2000. Prior to joining NARA, he served for 10 years as the Principal Scientist for Raytheon Information Technology Services and Hughes Information Technology Corporation working at the NASA Goddard Space Flight Center on the Cassini-Huygens Space Mission team. While there, he was responsible for the design and development of a sub-system for a miniaturized sensor (a gas chromatograph-mass spectrometer) on the Huygens probe. Dr. Navale earned an undergraduate degree in physical sciences, a Masters in Earth and Ocean Sciences, and a doctorate in Chemistry from George Washington University. He has over 20 research publications and was the recipient of the 1998 NASA and the European Space Agency award for outstanding contributions made to the Cassini-Huygens mission and the recipient of the 2005 NARA Archivist Award for outstanding contribution to organizational goals of the agency.
