500TB Could Be Stored on a 5D Optical Disc for Billions of Years

Описание: 500TB Could Be Stored on a 5D Optical Disc for Billions of Years

This type of data storage uses three layers of nanoscale dots in a glass disc. The size, direction, and position of the dots indicate the five "dimensions" employed to encode data.

Lasers are used to add data on the discs, however, if the laser travels too quickly, the disc's structural integrity is jeopardised.

Although the study estimated a maximum data rate of one million voxels per second, each bit in 5D optical systems requires many voxels.

Although this research is still in its infancy, the team was able to create and recover 5GB of text data using a 5D optical medium.
