"Storage expert warns of short life span for burned CDs
And don't count on hard disk drives for long-term storage, either",
JANUARY 10, 2006
http://computerworld.com/hardwaretopics/storage/story/0,10801,107607,00.html
"If you want to avoid having to burn new CDs every few years, use
magnetic tapes to store all your pictures, videos and songs for a
lifetime.
.....
"Unlike pressed original CDs, burned CDs have a relatively short life
span of between two to five years, depending on the quality of the CD,"
Gerecke said in an interview this week."
Gerecke氏は physicist and storage expert at IBM Deutschland GmbHです。
Hard-drive disksに対しても悲観的で、結論的なものとして:
"To overcome the preservation limitations of burnable CDs, Gerecke
suggests using magnetic tapes, which, he claims, can have a life span
of 30 to 100 years, depending on their quality."
テープのメディアは理論的に良いとしても、I/Oパフォーマンスがアレだし、
メカニカルな障害も怖いです。
