That's enough data to store over 40,000 DVDs, or over 100 years of watching one movie a day. As [*IEEE Spectrum* reports](), that's around 4,000 times the data density of a Blu-Ray, and roughly 24 times of the highest-capacity hard drives currently available. Instead of just allowing you to live out the rest of your life watching movies without having to swap out the dis**c**, the researchers are hoping their invention could significantly shrink the size of data centers — which still [rely heavily]() on huge numbers of conventional hard drives. Best of all, the researchers claim their discs could make use of conventional DVD mass production methods, producing a single disc in only six minutes. ## Laser Blast Instead of storing data in a single layer, the team came up with a way to encode data across 100 layers. As detailed in a [paper]() published in the journal *Nature* last week, the data is also recorded in spots that measure only 54 nanometers across. To both write and read data, the researchers relied on nanometer-scale lasers. By finely timing the system, they were able to significantly pare down the size of the spots where the data is stored. The light-sensitive material that enables all this, called AIE-DDPR, has been a "ten-year effort," as coauthor and University of Shanghai for Science and Technology computer engineering professor Min Gu told *IEEE Spectrum*. To be clear, it's unlikely that these super-high-capacity optical discs will bring Blockbuster back from the grave, given the decades-long and [painfully drawn-out]() death of physical media. Nonetheless, Gu and his colleagues believe their optical discs can be manufactured at commercial scales, making them an intriguing option to scale down the physical space taken up by data centers. **More on renting DVDs:** *[Startup Says It Can Store 100TB in Nintendo-Like Cartridges]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
