Shanghai boffins stuff petabit on optical disk

Stefan Mileschin · 26th February 2024, 07:40

A bunch Shanghai boffins have used a tiny laser to cram loads of data onto a disk.

The final result is a disk with a 3D stack of data layers that can hold a petabit (Pb) of information - that's the same as 125,000 gigabytes of data.

This is a mad amount of data compared to what can fit on even the fanciest flash or hybrid hard drives (HHDs).

That same petabit of information would need a stack of HHD drives as tall as a man - if you tried to put the same amount of data onto Blu-rays, you'd need about 10,000 blank ones to do your pretty pants challenge.

To pull off their feat, engineers had to make a new material for their disk's film, called "dye-doped photoresist with aggregation-induced emission luminogens."

AIE-DDPR mixes special, light-sensitive molecules that can soak up photonic data at a tiny level, which is then written using a high-tech dual-laser.
