Did you ever stop to think a bit about a way of preserving our heritage? During the Cold War, fearing an imminent nuclear war, people used to build the so-called time capsules. Others would look upon the oral tradition and there are those who seek the help of technology. 5-D glass disks will preserve our knowledge for eternity, even after the Sun will go out.
A team of British scientists from the University of Southampton was successful in devising a series of coin-like glass disks which are capable of storing more information than any storage device previously created.
If you thought that a hard disk of 1 TB is big, then you were wrong. According to the paper published upon the subject, one glass disk is able to store approximately 360 TB worth of information. The disk was manufactured from a special type of quartz and the information is encoded on the disk using a laser beam.
Furthermore, the novel data storage device is roughly the size of a coin and it was built to last approximately 14 billion years in outer space conditions. But, theoretically speaking, the disk could last forever if it is kept at room temperature.
The study regarding the creation of the data disk was presented on Wednesday, during the International Optical Engineering Conference.
So, what does the 5-D stand for? According to the paper, the team used a five-dimensional technique in order to craft the capacitive data disk. This means that apart from height, width and length, the scientists also included size and spatial orientation. The result is a coin like, ultralight and ultra-capacitive storage device that makes an external hard-drive look like an ogre struggling to carry an aspirin.
Peter Kazansky, the senior researcher, declared he is absolutely thrilled to have created such a device that is capable of storing all that we’ve learned so far. He also declared that he and his team of scientists are currently working on a way to commercialize the device.
These 5-D glass disks will preserve our knowledge for eternity if kept at room temperature. Initially, the devices were designed in order to withstand temperatures up to 190 degrees Celsius. Moreover, the scientists are thinking of sending a series of glass disks into space, arguing that when mankind is no more, this would be the safest place to store the precious data disks.
Furthermore, Kazansky also declared that up until now he was successful in encoding multiple texts on the glass coin-like disks, including Opticks by Isaac Newton, the King James Bible, and the Declaration of Human Rights.
