How can quartz store data

In Quartz glass, we can Access data non-sequentially, which is one of the best advantages when compared to a Tape drive, where we can access the data sequentially, which takes more time to retrieve the data.

By using Ultrafast laser optics and artificial intelligence, we are storing data in quartz glass. Femtosecond lasers — ones that emit ultrashort optical pulses and that are commonly used in LASIK surgery — permanently change the structure of the glass so that the data can be preserved over a long period of time.

A laser encodes data in glass by creating layers of three-dimensional nanoscale gratings and deformations at various depths and angles.

A special device — Computer-controlled microscope is used to read the data. A Piece of Quartz glass is placed in the read head and to begin with, it focuses on the layer of interest, and a set of polarization images are taken. These images are then processed to determine the orientation and size of the voxels. The process is then repeated for other layers.

The images are fused using machine learning. To read the data back, machine learning algorithms decode the patterns created when polarized light shines through the glass. ML algorithms can quickly zero in on any point within the glass, which reduces lag time to retrieve information.

By using Quartz glass, we are able to store the data permanently for life long. We can store Lifelong medical data, financial regulation data, legal contracts, geologic information. By using this, we can Pass not only data, entire information to the future generations. Defense , Information Technology. Missile Guidance and Control Systems. Health , Healthcare.

Computer Hardware Computer Hardware and Future. We live in a time when technology dominates our lives. More and more of our personal data is stored on digital devices including mobile devices, PC, camera, servers, and others. The sad truth is, no medium for data storage lasts forever. For example, magnetic data tapes has an estimated lifespan of up to 10 years.

Storing person data on flash drive or cloud server may be fine for most practical applications. But, what if you need to store or archive important data, for example, the United States Constitution, for hundreds of years?

Thanks to a new discovery by U. Digital storage is incredibly easy and practical, but it has the downside of being prone to data loss.

A book stored on your hard drive might last less than a hardcover. Solid state drives last a tad longer, but after a number of read-write cycles these too will inevitably fail. Now, for most practical purposes this can be fine, but if you need to store important data for … hundreds of years? This might seem absurd, but national archives are very serious about it and invest a lot in networks that backup data over and over. There might now be a more elegant solution after a team reports how they managed to cram TB worth of five-dimensional 5D digital data onto a small quartz disk.

The researchers claim the data is stable for as long as
