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 capacity of about 15,000 DVDs.

Optical discs, such as DVDs and Blu-ray discs, are durable and inexpensive. A standard single-layer Blu-ray disc can store 25 gigabytes. By comparison, some USB flash drives can store 1TB, and hard disk drives (HDDs) can hold up to 16TB.

But a team of scientists has created a new type of material, called "dye-doped photoresist with aggregation-induced emission luminogens" (AIE-DDPR) with a high areal density (the amount of data that can be stored in a given area) that can offer far denser storage capacity than typical HDDs).
