It's a gift from the University of Southampton where scientists have made a major step forward in the development of a type of digital data storage that is capable of surviving for billions of years.
Now major documents from human history such as Universal Declaration of Human Rights, the Magna Carta and the Kings James Bible have been saved as digital copies that could survive the human race.
Canon Edward Probert, Canon Treasurer and Sub Dean of Salisbury Cathedral, told Premier: "This is an absolutely novel form of storage.
"Having this really early instance of this completely new form of storage is quite a lively way of invigorating our archives."
"What's striking about this new form of technology is that it's not going to corrupt - it's going to stay in perpetuity as it is - you can't really destroy this form of recording.
"So it's a perpetual record and actually it would be a very fine way of storing Biblical materials and so on."
The documents were recorded using ultrafast laser which produces extremely short and intense pulses of light.
The file is written in three layers of nanostructured dots separated by five micrometres (one millionth of a metre).
The Magna Carta was sealed 801 years ago and on the same day the cathedral will be hosting a special discussion on the European Union referendum.
