The drive is capable of storing information

passed thousands of years people have gone from rock art, and are still the most reliable way of storing information are stones. Engineers Japanese company Hitachi introduced the drive is capable of storing the information recorded on it indefinitely. The drive is used as a thin plate of quartz glass, which withstands high temperatures, radiation and various types of other adverse factors completely without losing its physical svoystv.

The principle is similar to the record store information on CD \ DVD discs, when the data in binary form by creating dots recorded in a thin sheet of quartz glass. Reading data can be carried out by a conventional optical microscope. All that is needed - is a computer and software that will decode the binary. Now prototype storage device of Hitachi a quartz glass plate, measuring 2 centimeters by 2 centimeters and a thickness of 2 millimeters. The recording density of data on the single crystal layer of the "drive" is about 40 megabytes per square inch.
