Sony’s push to get enterprise users to store data on optical discs has received added momentum with its acquisition of a Facebook-linked startup focused on optical storage. Led by former ...

TDK's 10 layer, 320 GB Blu-ray disk is a remarkable technical feat. Too bad it will never be a commercial success. Optical is a dead end - and soon it will just be dead. Here's why.

Most optical memory storage methods developed in the past, including CDs and DVDs, are limited by the diffraction limit of light. A single data point cannot be smaller than the wavelength of the laser ...

Given a 532 nm laser, then the maximum storage density on a disc surface is limited to 3.5x10 8 bits/cm 2. If data is encoded in all three dimensions, then the data density can reach as high as 6 ...

As the technology world has been moving on from optical media these past few years in favor of digital downloads and flash storage, it would seem that DVDs are becoming a thing of the past. Only ...

Hardware Storage Researchers have developed a Very Big Disc™ that can store up to 200 terabytes of data and may represent a return to optical media for long term ...

New optical tech could slash archival costs by 10x or even more Optera Data’s discs could hit 10TB for just $1 - cheaper than tape! The low-power, high-density storage has data centers in mind ...

Researchers at the UK’s University of Southampton are working on a five-dimensional optical data storage medium that could hold the equivalent of 10,000 times more data than a single Blu-ray disc.

Last year, Facebook said it had built a cold storage system from 10,000 Blu-ray discs. The system holds a petabyte of data and cuts costs by 50 percent and energy use by 80 percent compared to a ...
