How long do you think your DVD or memory stick will last? If you are really serious about keeping your information for the next few centuries and millenniums to come, then you might be delighted to know that Hitachi has develop a new technology which enables their recording medium to last for 100,000 years!
Nikkan Kogyou Shimbun reports that Hitachi has created this new technology by using recording data using precision laser etching on fuzed silica. However, there is a drawback because 3-centimeter square block of silica can only write about 4.8kilobytes of data >_<
I wonder who did the scientist know that it would last around 100,000 years? In fact, even if they make such a huge claim and someone discover that it only last for 80,000 years, I’m sure the inventors wouldn’t be around any more.
But then again, I think they should just concentrate on making memory medium that simply last for 1,000 years. I think that would be more than sufficient.
You know, I distinctively remember a time when CDs were promoted as the future of data recording over magnetic tape, and that it can “last forever”.
But of course, now we know that CDs are anything but indestructible. The plastic can degrade.
Let’s just say I am skeptical of any more eternal storage mediums…
this technology must have first been made around the time of the dinosaurs.
You know….to prove that it lasts 100000 years.
