Hitachi showed a prototype experimental data storage in digital form, relying on a carrier such as silica glass. According to the developer, Hitachi’s new storage system technology saves the information in its original form for “hundreds of millions of years.”
On the eve of a research unit, Hitachi showed storage solution that includes a square glass area of 2 sq/ cm and a thickness of 2 mm, which can be up to 40 megabytes of data. In terms of density per square inch Hitachi storage system almost complies with the standard CD.
Hitachi developers said that, the data is written in binary format using the so-called laser points, located in the quartz glass with four layers. The glass is easily possible to add additional layers, increasing the recording density. “The volume of data generated every day are growing, but today there are almost no solutions that can save the information at least a couple of generations to come.
Recently, the industry really has a problem of long-term data storage. Modern CD and film system can store data at best a few decades, and in most cases they cannot store data longer a dozen years, “- says the engineer Hitachi Katsioshi Tory. According to him, the new system is writing data, heating quartz glass with a thin laser to 1000 degrees for two hours, then this carrier are not afraid of any radiation, nor water, nor the majority of chemicals, and the recorded data can be read, even after hundreds of millions of years. “This glass will hold it for as long as you do not destroy them physically,” – says Tori.
Engineer says that another advantage of the Hitachi’s new storage system’s design is the method of writing data. It is a simple binary sequence, which can be considered not only with special equipment, but in an ordinary microscope. We believe data will survive unless this hard glass is broken, researcher Takao Watanabe was quoted as saying.
Experts from Cornell University, USA, published a study which said that the average life species on Earth is 10 million years old, so new media in theory could leave data on people even after the disappearance of the latter with the Earth.
