That’s 10,000 times more data than Blu-ray discs … Just imagine that! 500 TB of data on a single compact disc the size of a CD. Woah, Mind blown~!
Taken from Engadget … Using high-speed lasers, researchers have created “5D” data storage technology that could allow 500 TB of data to be written to a CD-sized glass disc, according to the Optica society. The technique uses higher writing speeds that might finally make it feasible to use the technology for archival and other purposes.
With 5D optical storage, each file is uses three layers of nanoscale dots. The dots’ size, orientation and position within the three standard dimensions, make up the five “dimensions.” The dots change the polarization of light travelling through the disc which is read using a microscope and polarizer.

Using the new technique, the team was able to write 5GB of text data ono a silica glass disc the size of a conventional CD with nearly 100 percent readout accuracy. “With the writing density available from the method, the disc would be able to hold 500 terabytes of data,” the researchers said. They were also able to write at speeds or around a million voxels per second, or about 230 KB per second.
