"Revolutionary Optical Disc Stores Petabits of Data, Redefining Storage Capacity"

Scientists have developed a DVD-sized disc capable of storing up to a petabyte of data, equivalent to over 220,000 regular DVDs, by utilizing a special coating and 100 layers. This breakthrough could revolutionize data storage, potentially allowing for millions of hours of video to be stored on a single disc. However, challenges such as slow writing speed and high energy consumption need to be addressed before widespread use.
