Revolutionary Optical Disc Technology Unveiled: 1 Petabit Capacity

Researchers in China develop a DVD-sized disc that can store up to 1 petabit of data, potentially transforming data storage and reducing data center sizes.

A team of photonic engineers in China has created an optical DVD capable of holding a petabyte of data, equivalent to 1 million movies or 2000 PS5 games.
The new technology utilizes a 3D planar recording architecture, allowing for data storage across up to 100 layers on a single disc.
The discs are expected to last between 50 and 100 years, offering a sustainable solution for the digital economy.
Challenges remain in terms of writing speed and energy consumption, but researchers are optimistic about commercialization prospects.
This breakthrough could significantly reduce the physical and energy footprint of future data centers, making it a game-changer for various industries.
