The downtrend graph of the recordable optical disc market reveals a CAGR of -1.40% from 2024 to 2034. Reading the numbers, it ...

These new optical disks, while expensive, would make it possible to store all the 5.8 billion indexed web pages that power ChatGPT, in the kind of CD binders we used to carry around in the 90s.

The traditional way to cram more data onto optical disks, such as DVDs, is to create smaller features on their surfaces using lasers with shorter wavelengths. The latest storage media, such as Blu ...

Here’s how it works. Scientists have developed a new type of optical disc that can increase information storage capacity to the "petabit" level — 125 terabytes of data, or the combined storage ...

The most common types are CD, DVD and Blu-ray. As removable media, optical discs superseded the earlier magnetic disk cartridges because they weigh less, have higher capacities and are not subject ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Even in a digital-first world, optical disks like DVDs and Blu-rays ...

A three-dimensional nanoscale optical disk memory with petabit capacity has been developed at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences. [Photo/CCTV ...

As New Scientist explained on Wednesday, a diamond optical disc can store the same amount of information as roughly 2,000, same-sized Blu-rays. What’s more, researchers need to ensure all that ...

Optical disks and magnetic tapes are suitable media for the long-term storage of large amounts of data. We are developing thin optical disks using paper-thin 0.1-mm-thick substrate as a means of ...

A major development in the production of optical discs has happened this week. Scientists at the University of Shanghai have unveiled a new form of optical disc that can hold up to 200,000 gigabytes ...

Using 3D storage techniques, scientists at the University of Shanghai for Science and Technology developed an optical disk capable of accommodating 1.6 petabits of data (that's 1.6 million gigabits).

Around a decade ago, you gave up on burning optical discs, and switched to storing your files on portable hard drives. One local, one off-site, and a cloud backup just to be sure. You’re ...
