Hard Disk Super Can Hold up to 10 Million Years

A good-quality hard disk can last for several years. However, at the end of this mechanical data storage medium will be damaged which could potentially destroy all data on it.

Estimate the lifetime of the hard disk (Mean Time Between Failure / MTBF or lag time before the damage) has been established since leaving the factory, usually in a matter of hundreds of thousands of hours.

Then, how to keep data stored on the hard disk remain durable in the long term? Well, the research team from the local control of the French nuclear waste Andra has made a prototype of a hard disk lifetime is very long, reaching 10 million years.

Purpose of the creation of super durable hard disk that is giving information to people in the future who happens to find the location of nuclear waste disposal Andra. More or less describes the content of the information about nuclear waste is buried at that location and the correct way of handling.

Hard disk is made of super sapphire and information in it was recorded through platinum sculpture. Amounts of data storage disc two, each measuring 20 cm. The cost of manufacture reached 25,000 U.S. dollars. Approximate age of the hard disk is obtained through simulation aging by immersion in liquid hard acid.

In addition to the type of material, the difference this super hard disk with a regular hard disk includes data recording methods. Hard disks used to record digital data in the magnetic pattern, while the hard disk stores data Andra cardboard sculptures in the form of very small-sized image.

One disc can hold approximately 40,000 images. The people in the future computers will not be needed to read the data in it. All it takes is a microscope.

Even the hard disk has made a very durable, there is still a problem to be solved by researchers Andra before place it on the set of nuclear waste. "We do not know the information must be written in any language," said Patrick Charton of Andra.

The issue of this one was somewhat complicated because of the language used to communicate would have changed much over millions of years. While the information in the hard disk must be understood by anyone who found it in the future, if ever man was still tangible.
