  2. Magnetic Tapes News • “IBM researchers set world record in magnetic tape data density” • San Jose 16 May 2006 • “IBM researchers have demonstrated a world record in data density on linear magnetic tape, a dramatic indication that one of the computer industry's oldest and still most affordable data storage technologies has the potential to provide increased capacity for years to come.” • “... packed data onto a test tape at a density of 6.67 billion bits per square inch - more than 15 times the data density of today's most popular industry standard magnetic tape products...” • http://www.hoise.com/primeur/06/articles/monthly/AE-PR-06-06-91.html

  3. New Laws • Sarbanes-Oxley Act of 2002 and the Health Insurance Portability and Accountability Act of 1996 • Both require businesses to keepinformation... lots and lots of information • May never use it. But need to keep it for the day those auditors come around... • Tapes are 1/5 to 1/10th the cost of disk drives • (And, when not in use, use no power.)
