What does 5D Storage do?
5D optical data storage (sometimes known as Superman memory crystal) is a nanostructured glass for permanently recording digital data using a femtosecond laser writing process. The memory crystal is capable of storing up to 360 terabytes worth of data for billions of years.
How does 5D optical storage work?
The 5D optical storage medium works by using an extremely fast and precise femtosecond laser to create tiny pits within the fused silica glass containing self-assembled nanostructures (nanogratings). Quartz silica glass is the same material used to make spacecraft windows and is extremely durable in space.
Why is 5D storage important and relevant to us?
Researchers say revolutionary 5D optical storage could protect hundreds of terabytes of data for billions of years, far beyond the capabilities of current storage media. In 2013, researchers from the University of Southampton demonstrated the ability to store a 300 KB digital copy…
Can I store 500tb for billions year?
A new high-speed laser writing method claims that it can pack 500 terabytes (TB) of storage onto a single CD-sized glass disc. That equals somewhere in the neighborhood of 125,000,000 photos.
What is optical storage?
optical storage, electronic storage medium that uses low-power laser beams to record and retrieve digital (binary) data. In optical-storage technology, a laser beam encodes digital data onto an optical, or laser, disk in the form of tiny pits arranged in a spiral track on the disk’s surface.
Can data be stored in crystals?
The scientists use a sophisticated laser to encode the information into minuscule formations, known as nanostructures, inside fused quartz. The structures alter the way light travels through the glass, allowing the data to be read by special optical devices.
What is the latest optical storage technology?
The Blu-ray disk has emerged as clear leader in today’s optical storage market. Unlike CDs and DVDs, which use a red laser to read and write data, a Blu-ray disk uses a blue laser, which dramatically increases capacities and data transfer rates over CDs and DVDs.
What is the disadvantage of optical storage?
Optical storage: Blu-ray disk More expensive than DVDs. Requires a Blu-ray player. Can lose data when scratched.
What are the disadvantages of using optical storage?
Due to its size, the optical disks are more prone to loss and theft. Optical disks cost more per GB/TB than any other forms of storage drives. And it too have very little storage capacity compared to them. Unless it is a Blu-ray disk, the maximum storage the Optical disks can offer is 4.7GB.
